Do you need to get some work done around the home? Maybe you need to drill some holes in a brick or concrete wall. Or maybe you need to hang some pictures or mount something heavy in a hard surface. Or, you need to drill some holes through a hard surface for plumbing or wiring. The point that we are making here is that you need the right tools for the job. So lets do a hammer drill vs impact driver to compare and see what each power tool is best suited for.
You can’t use a normal drill to work with brick, concrete, and other such materials. A normal drill would fall to bits, burn out, catch on fire, and just would not be a very good choice to go with. Maybe you already know all of this and you just want to read up on it more. Or maybe you are an aspiring handyman and need to know everything you can about your field of work and the tools you will need to use.
We are here today to talk about two specific tools, those being the impact driver and the hammer drill. These might sound like some kind of fighting moves used in professional wrestling, and while they might very well be just that, they are both useful tools as well. Now, with that being said, both of these tools have very different features and purposes. Today we want to talk about the difference between a hammer drill and an impact driver so you know exactly what each of these tools are for and what their intended purposes are.
The first tool that we want to talk about is the hammer drill. The hammer drill, just as it sounds, is more or less a combination between a hammer and a drill. Drills can be used for drilling holes and screwing screws into softer materials, usually wood. Also, hammers are used to hammer nails through softer materials like wood. However, both the hammer and the regular drill could not deal with harder materials like masonry, brick, concrete, and other really hard materials.
This is where the hammer drill comes into play. It is a tool that is primarily designed for drilling holes in hard surfaces like drywall, sheetrock, brick, concrete, and other forms of masonry. In terms of the motion of it, the hammer drill combines the spinning motion of a drill with the hammering motion of a hammer. This is shown to be the best way to drill holes through masonry. The combination of rotational and impact force really gets the job done.
The impact driver is quite different from the hammer drill. Whereas the main purpose of the hammer drill is to drill holes through hard materials, the impact driver’s main purpose is to drive big, thick, and long screws into really tough materials. These materials could be hard wood, studs, brick, concrete, and other forms of masonry. A normal drill simply does not have the power, the engine strength, the rotational capacity, or the durability of an impact driver.
The impact driver is pretty much a drill on steroids, one meant to deal with really hard materials. So, just to recap, the impact driver is all about driving long screws through tough materials, whereas the hammer drill is meant for drilling holes.
The tools are somewhat similar, but they are also quite different, as you can see. Unlike the hammer drill, the impact driver does not use any impact force, which is kind of counterintuitive due to the name of the tool. However, the impact driver only uses rotational force and does not use a hammering impact like the hammer drill. It might sound a bit confusing, but a hammer drill uses both rotational and impact force, whereas an impact driver only uses rotational force to get the job done.
Now that we have covered what the main intended purpose for each of these tools is, plus how they function, let’s talk about some of the other main differences between them right now.
One big difference between both of these tools is that the impact driver and hammer drill use different bits, or at least one of these tools is much more versatile in the type of bits it can accept. Impact drivers are very one faceted and have a locking head that only accepts hexagonal shank bits, but these do just fine for their intended purpose. On the other hand, the hammer drill can also accept round bits, as well as the hex bits, which is thanks to its 3-jaw chuck.
What you might not know is that hammer drills have a button to turn the hammering motion on and off. Therefore, the impact driver is like a hammer drill without the hammering motion, but the hammer drill does come with the option to have the hammering turned on and off. What you should also know is that impact drivers tend to produce a lot less vibration and noise than a hammer drill. The hammering motion from the hammer drill is very loud and the vibration it creates means that you really have to have a good grip on the hammer drill.
The two tools also differ in their shape. The impact driver is usually quite short and stubby, unlike the hammer drill which tends to be a little bigger and more elongated. At the same time, hammer drills have big internal clutches, whereas impact drivers don’t have these, making them a little easier to operate, especially for beginners.
As you can see, both the hammer drill and impact driver have their own specific purposes, both of which are quite different. It is understandable that people confuse these two tools, but they are really not the same at all. Hammer drills are great for drilling holes through hard surfaces whereas impact drivers are meant for getting big screws through those same hard surfaces.

Today we are here to talk about drill and a driver. Both of these tools are things that any handyman should have in their arsenal. While they may sound like similar tools, and in some regard, they are similar, they are quite different. This is very true when it comes to their purpose and function.
If you are an aspiring handyman, handywoman, carpenter, repairman, builder, or any other kind of professional where you are drilling and screwing, you will want to know the difference between a drill and a driver. While they both do the same thing in the long run, the real difference is the power they have and what materials they are designed to work with.
This information is important to know even if you just want to fix some things around your own home. Using a driver for something that a drill could do is more or less a waste of energy, whereas using a drill for something a driver should be used for is going to end in disaster, probably the death of your drill. At any rate, let’s get right to it. What the difference is between a drill and a driver is what we are here to clear up right now.
One of the biggest differences between these two tools that you need to be aware of is what they are used for. A normal drill is used for drilling holes into wood and other softer materials. The drill can also be used for screwing screws into wood, or even into pre-drilled holes. In other words, the drill is meant mainly for smaller purposes and softer materials. Drills just don’t have the power or force to handle thicker, harder, and denser materials.
On the other hand, a driver is used for drilling holes and screwing big screws into very hard materials. The driver uses a slightly different motion and has quite a bit more power, and is therefore easily able to make its way through concrete, brick, and other kinds of masonry. In other words, a driver is pretty much just a beefed-up drill with added power, one that is intended to handle the hard materials that a normal drill just cannot deal with.
Keep in mind that you should not use a drill like a driver, and you should not use a driver like a drill. Using a driver on soft wood will most likely pulverize and ruin the wood, something you obviously don’t want. On the other hand, using a normal drill to try and get through something like concrete is likely to result in a broken drill bit, a burnt out motor, and big headache for you.
Something else that is important to cover here is that both of these tools have a different motion, which is, in part, why they excel at different tasks. To start, a drill uses pure rotational force to get the job done. The pressure that is applied to the wood you are drilling all comes from you. Therefore, you can dictate exactly how much pressure you are applying to the wood. The most important thing to keep in mind here is that drills just turn, but they do not apply pressure, which is what makes them ideal for softer materials.
On the other hand, a driver, while also using rotation force, also uses impact pressure to get the job done. It moves back and forth, as well as front and back, really fast, thus creating lots of small impacts that chip away at masonry. This front-and-back motion combined with the rotational force is what allows drivers to work their way through hard materials like sheetrock, brick, concrete, and other such materials.
Just like with any other tools out there, both the drill and the driver have things they excel at and things they are not so good for. So, let’s quickly talk about the pros and cons of the both the driver and the drill.
As you can see, while both of these tools may look the same, they do work in different ways. All in all, they may be quite similar, but a driver is just way more powerful and adept at working with hard materials. For further details and reviews on some of the best power drills click here.
Drilling is no easy task, and it is not a job for everyone. But just how difficult is it exactly to drill on hard surfaces? Do you need a hammer drill for concrete? What are the best ways to drill on hard surfaces? These are some of the questions many people ask when they are not experienced in doing this job. If you are wondering about the complexity of placing holes on various surfaces, then this article is perfect for you.
Just how difficult is it to place a hole in various things like wood, cement, and concrete? For those who still have to do their first drilling job, it would be a good idea to know how each surface or material differ from each other, so you would know what it is you will be working on.
For starters, some materials are harder to work on than others. For example, mortar, brick, and concrete are tougher materials when compared to standard brick or cement.
Brick is often made from clay which is pressed into a block. This material is hardened by heating it up in a kiln. Sometimes other elements are added to the brick such as hydrated silicates, sand, and iron, which makes them tougher. These days bricks are often used for decorative purposes as they break easily.
On the other hand, cement is made up of mineral powder that has a fine texture. Adding water will create a pasty-looking element, which can be used to glue something together. It has various uses and is easy to drill.
A mortar has cement as its main ingredient. Lime or masonry cement can also be added to it and is often used as a binding substance.
Concrete is a blend of different materials such as gravel, crushed stones, and sand. These ingredients are glued together using cement. As wine tastes better with age, cement becomes stronger as it gets older. The concrete is hard to drill through given the many ingredients used to make it.
Given the toughness of concrete, it would be ideal to have a drill that can do the job as easily as possible. The drill that is perfect for concrete should have a variety of features such as variable speed, a hammer function, depth setting, and a good grip for additional strength.
With the need for all these features, do you need a hammer drill for concrete? The answer is yes if you want to lessen the time necessary for the job and to make the task much easier.
This is the reason why handymen and construction workers invest their time and money in buying one. The benefits of a hammer drill would outweigh the costs of getting one. However, if the costs are too high for you or if you only need to use it several times, then you may want to consider just borrowing from someone.
In cases where one needs to drill through concrete but is unable to buy or borrow one, do not fret. Using a hammer drill is not the only way to finish the task. There is an alternative to using this high-power equipment. However, it will eat up some time and is indeed tedious.
Contrary to popular belief, a hammer drill is not the only kind of drill that can get through hard concrete. A high-quality masonry bit drill will also do the job. There is a big difference between these two drills as the normal one does not have the hammer action, and thus users will need to turn the speed up during the drilling process.
There are some tips for using this trick. For starters, one has to have some water on hand, which has to be regularly used to prevent the bit from the excessive rising of temperature.
Using water will also help lengthen the life of the bit.
One also has to be mindful of damaging the chuck of the drill by avoiding grinding the drill up and down. Plus, there is a need to remove the dust and take away the drill’s flute constantly.
So, what kind of drill bit should be used when drilling through concrete? The masonry bits are the only one that can do the task as the primary component of this bit is made from steel.
Many people end up with messy holes. The secret to having clean-looking ones is to use the small bit first until you reach your required diameter or measurement. The time spent in drilling holes using this tip vary depending on the material you are drilling through. For example, it would take longer to drill a clean hole in wood but would be faster if one is drilling against a metal.
Setting the speed can be quite tricky, too, since the speed to be used depends on the material being drilled. For example, slower speed must be used for drilling into metal while higher ones for concrete. Sometimes, one must use some oil to lubricate the material.
Those who are experienced in drilling make the task seem so simple and easy to do. Unfortunately, the job is a tough one. Many people believe that drilling holes are all about placing a drill bit on the chuck and pressing the trigger. However, drilling is a skill that takes practice. If one does it hastily and sloppily, then a blow-out might happen. Some even end up breaking their wrists and burning up the drill bits. Thus, one must put some eye protection gear for safety purposes.
Moreover, one of the fundamental things to remember is to allow the drill to its job. This means not putting too much force on the drill or pushing it too hard against the surface. Failure to follow this tip may result in breaking the drill bit you are using.
Spring is here, and that can only mean two things.
The wife has everyone on spring cleaning detail around the house, and she’s got you doing projects. Ugh!
All the tools in the garage are buried because you haven’t touched them since the fall. Forget it! Just go out and buy some new ones.
If you’ve recently bought a new power drill, just a heads up – they are better than ever! If you want to learn the ins and outs of the drill, read on to become an expert!
Don’t be embarrassed if you’re not sure. This might be your first time purchasing one.
Think of it as a screwdriver on steroids. You can attach different “bits” to it, to match whatever screw you’re working on. You can also attach “drill bits” which allows you to drill holes in things.
For example, maybe hanging a heavy picture on a wall or putting up shelves in the kids’ room.
What will they think of next?
Now that you’ve purchased the drill, it’s time to figure out how the heck it works. The main thing to remember is that you can swap out the bits (head ends). Most of the modern power drills tighten by leverage.
The power drill also has two other important components.
The most common is the general-purpose ones that come with a simple head. This can be used for most of the projects around the house.
Other bits include spade and flat (if you plan to do some construction around the house), masonry (for concrete), and bits with diamond carbide tip (for drilling into porcelain).
If you don’t want to drag around a pesky cord, consider going cordless. This drill typically comes with a battery and a charger, and some kits can even include batteries.
A cordless drill also has the forward, and reverse settings and most have a variable speed trigger. Be aware that the more pressure you put on the trigger, the faster the bit spins.
Same rules apply to a corded drill – wear safety goggles or any protective gear. Power nailers accounted for about 37,000 emergency room visits in recent years – don’t add on to it!

Every man and woman out there will agree that a healthy household requires proper maintenance and care. This means either hiring contractors for rudimentary maintenance and upgrades or taking matters into their hands. Owning a power drill and a toolkit built around it might eliminate this problem. Hence, what is a power drill used for and how to pick the right one will be the topic of this piece.
Generally speaking, a power drill is an incredibly versatile power tool. It can either be corded or cordless. The basic concept is a rotating motor and different heads which are held in place by a chuck. This concept varies from product to product, with different attachments being better or worse for certain tasks.
For instance, there are attachments which allow the user to drill or drive at an angle, to get better torque, or to be more reliable. Most drill manufacturers have compatible attachments on availability, so the user will only have to do a bit of project-related research to get the best tools for the job.
Generally, a power drill is used for drilling holes and driving screws, but think of it this way: this is a tool with swappable attachments in a world filled with mad geniuses and creative individuals. There are a few numbers of uses for power drills out there, the only limit is how much time can one put into research. So, owning one makes a lot of sense for all homeowners out there.
Whether it’s a cordless drill or a 230V powerhouse, power drills are incredibly efficient, versatile and time-saving power tools. Coming in at different price points and in different sizes, it’s easy to get tangled up in the complex hardware and power tool market.
Getting the right attachments for the right project will certainly make tasks a lot easier to finish. There is a lot to explore about what is a power drill used for and that is something that the industry has learned and adapted to as well as will continue to know.
A power drill is a great tool for setting screws. This tool saves a ton of time and muscle by making the job of setting screws a breeze. But driving a screw properly isn’t always as effortless as it might look.
One of the worst sounds on a job site or in your garage is the thuda-thuda-thuda or a driver bit camming out of a screw head. It means there’s an adjustment that needs to be made, and it also means someone is likely getting frustrated.
So what’s the secret of how to use a drill to drive screws? Keep reading to find out.
Do you want to learn how to drive screws perfectly? Follow this guide so you can learn all the necessary techniques.
The main thing to consider when wanting to drive a screw properly is to think about a straight line. This means maintaining a straight line through the shaft of the screw, to the bit holder, through the body of the tool, and right up through your arm.
The challenge with drilling a screw straight is the hinge point where the screw fits onto the driver bit. When applying downward pressure from the drill onto the screw, it’s all too easy for the screw to come out of alignment with the tool. This is why maintaining a straight line from the drill to the screw is so important.
This is the best way to get the screw started in straight. Simply place the screw on the bit, then take the screw and the tool, and jab the tip of the screw into the wood.
By doing this you’ve gotten a tiny bit of the thread started so that when you pull the trigger on the drill, the screw will already have a little bite into the wood fiber so that you’re ready to go.
Another option is to use a metal tap to get the threads started.
The last thing you want to happen when drilling in a screw is to strip the screw head. This happens for a number of reasons, like when you are using the wrong size driver bit or when applying too little pressure on the screw.
Stripping the screw head will ruin the screw, and will make the job of removing a screw that’s already been set a much bigger challenge.
The key to how to use a drill to drive screws properly is to focus on alignment. When setting screws with a power drill, make sure to maintain a straight line from the tip of the screw all the way up through your arm. Remember, when you start straight, it will finish straight.
Believe it or not, following these simple guidelines will make setting screws a piece of cake.
When your next home improvement task requires the use of a high-performance drill, you may need to decide if an impact drill is your new best friend.
The toughest part of your choice will be deciding whether an impact drill can do the job or if a hammer drill is necessary as well.
Thankfully, the decision is made easier when considering to the nature of the task at hand. Before you head to the store, you’re going to need to have a few things in mind.
Take a good look at the task you’re looking to complete. You can help your decision on which power drill is right for the job by planning the job out ahead of your shopping spree.
Ask yourself the following questions:
Each question helps you narrow down the choices available when you visit the power drill section at your local home improvement store.
Welcome to the fastest and most ideal power drill for securing screws, fasteners, and bolts with precision.
This remarkable product is available in a range of sizes but generally tends to be more compact and easier to fit into tight spaces.
Its clever design also allows for easier use, as the this drill is designed to utilize both strong rotational force and a hammer-like action when necessary to ensure a screw is placed exactly where it needs to be, and no further.
“…impact drivers typically deliver two to three times more turning force (torque) than the average drill/driver.” – Popular Mechanics, 2017
For those who would rather not waste their time, this can certainly speed up the process of getting fasteners in place without stripping them of their threading.
A hammer drill is not recommended for most jobs. This product is larger, heavier, and more cumbersome to operate, but it can also serve a singular purpose better than any other power drill; it is ideal for drilling into brick, concrete, and block.
While an impact drill is able to activate a hammer-like action when necessary, a hammer drill incorporates a full-time focus on utilizing a hammer-like action to help break up the surface you are drilling into.
Such an ability means it can smoothly and easily take on the task of paving the way for the use of a standard power drill, but it cannot serve the same purpose as a standard power drill.
The hammer drill’s action, if used to secure fasteners, can easily damage or strip a fastener’s threading completely, rendering that screw or bolt useless.
For this reason, among others, a hammer drill is better for creating new holes for fasteners to be placed in by the use of a standard issue power drill.
Whether you need the raw drilling power of a hammer drill, the sheer precision of an impact drill, or a combination of both, we’ve got you covered.

A drill is an essential piece of tool that can make house repairs, improvements and overall maintenance easier. In the world of power tools, a simple drill may offer many features that are lacking in the average drill. Examples of such would be the brushed and brushless drills. Between the two, many contractors, handymen, and DIY enthusiasts prefer using a brushless drill. That being said, what is a brushless drill anyway and why is it better?
Knowing the basics of what is a brushless drill and a brushed drill will help us identify and understand why most users choose the brushless drill.
A traditional, brushed drill is commonly run by a brushed motor consisting of four basic parts: a ring of magnets and carbon brushes that are in a fixed position even if the tool is used. The armature and commutator that both rotate on the motor shaft that is located within the magnets.
Once you supply the motor with power, a charge flows from the tool’s battery to the spring-loaded brushes. After which, it reaches the commutator which is responsible for directing the charge to the armature. Inside the armature, copper windings are magnetized because of the charge causing it to push against the ring of magnets surrounding it and forcing the armature assembly to spin. Basically, what it entails is that physical connection between the parts is required during operation.
A brushless drill, on the other hand, is run by a motor that does not require physical connections between the moving parts. Meaning, it has no brushes and commutator. Also, the magnets are located on the motor shaft while the copper windings of the armature surround the shaft and are stationary. Similarly, since it has no brushes and commutator, it uses a small circuit board instead to direct the delivery of energy to the windings. So, when you power up a brushless drill, the circuit board controls the entire spinning action.
Unlike a brushed drill that runs on a steady amount of energy, whatever material you use, a brushless drill is able to adapt itself accordingly. Hence, saving you energy in the process. Since a brushless drill uses a circuit board to communicate with the fixed windings directly, the drill is able to adjust itself according to the task at hand.
For example, if you are drilling a screw into a Styrofoam, it will be able to sense the lack of resistance coming from the material being drilled. This allows the drill to get a little charge off of the battery just enough for the task to get done. Likewise, if it senses that you are drilling a more resistant material, it will adjust again and draw more current from the battery.
You may have noticed that when you use a brushed drill, there is a tendency for the tool to become warm. Sometimes, it even becomes hot to the touch if your drilling requires extra torque. This is because the brushed motor inside the drill has brushes inside it that create friction by dragging against the commutator as it spins. As more energy is generated, more friction is created.
The physical contact results in a continuous waste of energy during the operation process which can quickly drain the battery. On the contrary, with a brushless drill, energy wasted through friction is essentially eliminated because there is none going on among the moving parts.
As such, energy pulled from the battery is solely for the task at hand; thus maximizing your battery’s stored power. Aside from longer runtime, no friction also means no problem with your drill getting hot and uncomfortable while you use it.
Compared to bigger brushed models, smaller designs of brushless drills can provide more torque value. Since there is no energy loss due to friction during operation, the circuit board can put as much power as it can to the current task. You also get the advantage of lesser weight, unnecessary power draw and noise reduction. Also, a brushless motor has its copper windings located on the outside of the motor configuration. Since there is room to make the motor larger, brushless drills can become more powerful overall.
Heat is the common reason why tools break down easily. With a brushless drill, there are no brushes to worry about, so your drill is virtually frictionless. This means less heat is emitted by the parts inside. With the components kept cool during operation, the motor remains stable and there is a slower rate of wear and tear on the tool, so you can expect a longer product life.
Brushless drills are also quite popular because of its quiet operation, especially if you need to work on a project in your home. Definitely, having a tool that will not drown your entire household in noise is a must. Again, this reduction in noise is due to the frictionless design of the motor.
Brushed drills are usually bigger and heavier than brushless drills since the motor inside them requires room for their components to move around. With frictionless mechanism behind the brushless drill, a smaller housing is possible without compromising the power of the tool. This also makes the brushless drill easy to carry around and use.
Power tools are generally more expensive than the average ones. In fact, power tools or drills with brushless motors are approximated to be 30% more expensive than standard cordless tools which makes it out-of-reach for the average person or household who will not be using it daily.
However, considering the added efficiency and features these tools offer, it is highly understandable. Likewise, brushless drills are also more comfortable to use and usually weigh less than the brushed one. Additionally, since they wear out slower, you will be able to use them for longer and save yourself from early breakdown and repair costs.
Nonetheless, even if brushless drills are still expensive to fit most budgets, a variety of options are available with different price points. Therefore, it is always best to compare different models to see which one is the best for you. In the end, investing on a power tool or not will depend on what suit your needs at work or your home.
One of the most common questions people have when it comes to drilling is whether it’s possible to drill into concrete without a hammer drill.
The truth is that yes, it can be done, but you must keep in mind that it’s not going to be an easy task.
When you need to drill into concrete, it’s ideal to have a hammer drill, but unfortunately, we don’t all have a hammer drill handy.
So, you’ve got to work with what you’ve got, right? If all you have is a standard cordless power drill, here are some tips for drilling into concrete with it.
Since concrete is a material that is made to last, it stands to reason that it’s going to be very strong. The reason it is so strong is because of the fact that about 65 percent of the mix is made up of sand, gravel, and aggregate.
So, when it comes to drilling, the very first thing you must understand is that you need to get through the aggregate. The only reason you’re going to be able to do this, especially if all you have is a standard drill, is to use a masonry drill bit, which is made to drill holes into concrete.
You should understand that if you are using a standard drill with a standard drill bit made to drill through metal, wood, or other such soft materials, you can kiss the bit goodbye. It will be worn down in seconds by the hard concrete and all you will have left is a stubby piece of metal in the chuck of your drill.
As we’ve already mentioned, if you plan to drill into concrete, you must use a decent quality quality masonry drill bit instead of your standard bit. If you invest in a set or two of various drill bits, you’ll have plenty of flexibility when it comes to choosing different size holes for your projects.
As you may have figured out, masonry bits are made to work with a hammer drill. In addition to turning like a standard drill, a hammer drill also hammers away at the concrete. However, since you don’t have a hammer drill right now, the only advantage you have is the turning action of your standard drill.
When you are drilling into concrete with a standard drill, it’s critical that you make sure you have water close by. After all, since you don’t have the hammering action that a hammer drill would have, your masonry drill bit is going to get very hot due to the friction created by the turning of the bit against the concrete.
In order to keep the drill bit from heating up too fast, you’re going to need to make sure that you are applying water to the drill site on a regular basis. This helps you avoid destroying your drill, so it will last longer for you.
When you are using your standard drill to drill into concrete, it’s necessary that you pull the drill out of the hole from time to time. This helps ensure that your masonry drill bit will create less friction and work more efficiently.
When you are trying to drill holes into concrete with a standard drill, it can be tempting to use a manual hammering action to move the process along. However, you must avoid doing this; you’re not using a hammer drill for this project, so you don’t want to treat your standard drill as if it is a hammer drill. When you use a manual hammering action with your standard drill, you’re increasing the risk of doing some serious damage to the drill as well as the drill bit.
Instead, you’ll want to remove the drill from the hole from time to time and clear out the concrete fragments and dust as mentioned in the “Things to Do When Drilling Concrete” section.
Here are six tips to keep in mind when you are drilling into concrete. This will help you save wear and tear on your drill and make your project run more smoothly.
Ideally, when you are planning a project that requires you to drill through concrete, you really need a hammer drill. However, not everyone has one, so it is possible to use a standard cordless power drill, as long as you have the proper drill bits to make the project run smoothly.
The process is fairly simple but choosing the proper tools and understanding how to use them will save you lots of time.
When you need to drill a hole into concrete, there are a few things you need to do before you get started.
Start by renting or purchasing a quality hammer drill. After all, you will find that drilling into concrete is so much easier with a hammer drill than a standard rotary hammer for a larger job. Hammer cordless power drills are designed so that they rapidly hammer to fracture concrete and the drill portion scoops the fractures out of the hole.
While it’s fine to use a typical rotary drill, keep in mind that the process will be much slower and harder – the concrete doesn’t shave into layers like metal or wood. Instead, you should be willing to pay for the rental of a hammer drill instead of using your rotary tool to drill through the concrete.
When you are drilling through concrete, you’ll find that it really is worth it to pay more for a hammer with more power from a brand that is well-established. Other beneficial settings include a comfortable grip, a second handle for your other hand, a depth stop, and a speed setting.
Once you have the hammer power drill, you’ll want to take the time to get to know it. Before you start using it, make sure that you have taken some time to read through the user’s manual so that you understand what the controls/knobs are for. You want to make sure that you are completely comfortable with your tool before you move on.
Make sure that you are following all safety precautions, including wearing eye protection such as safety goggles. This will help you prevent concrete chips from getting into your eyes. You want to also make sure that you are wearing heavy gloves and hearing protection as well. For larger projects that will result in lots of dust, you should wear a respirator.
You’ll want to insert a high-quality masonry drill bit into your hammer drill. These carbide tipped bits are made to withstand the force of drilling and hammering into dense concrete. Of course, you must make sure that the flutes of the bit are as long as the hole that you are going to be drilling.
These will be what directs the dust out of the hole. A rotary hammer requires a special drill bit, known as an SDS, SDS-MAX (for a hole up to 5/8” diameter, or a spline-shank for a hole that is ¾” or more).
If you are drilling through reinforced concrete and you need to drill deeper than the steel rebar, this will be much more difficult. In this case, you’ll need to use a special rebar-cutting drill bit once you hit metal. In order to avoid the drill overheating, you’ll want to slow down and take a short break from time to time.
It’s important to note that some drills do have a depth control bar or depth setting. If you have taken the time to read through your user manual as we have suggested, you’ll know the proper way to use your tool.
If there is no depth control setting on your tool, you can mark the appropriate depth with masking tape or a pencil mark. If you’re not sure how deep you should drill your hole, it’s important to keep the following in mind.
Make sure that you are holding the drill properly. You will need to hold it like a gun, with your index finger on the “trigger.” If there is a handle for your other hand on your drill, make sure that you use it. If there’s not a handle to put your other hand on, you will place it at the back of the drill.
At this time, you’ll want to mark the spot on the wall. You’ll want to use a soft pencil and mark a small cross or dot on the wall. Once you do this, it’s time to drill your pilot hole. You drill the pilot hole by placing your drill on the mark and drill briefly on low speed or in short bursts, if you have a drill that does not have a speed control.
The pilot hole is a shallow hole, no more than ¼” that will be the guide for your real hole. If your project will require the use of a large drill bit, you’ll probably want to consider using a smaller one for your pilot hole to increase the stability of your drill.
At this time, you will place your drill into your pilot hole, increase the power and, if your drill happens to have one, you can switch on the hammer function at this time. Make sure that you keep the drill perpendicular to the surface and drill using firm pressure to push the drill forward.
However, you want to avoid being too forceful with it. You will slowly increase the speed of the drill and if necessary, the force. However, you want to make sure that you maintain stability and control of the drill at all times. After all, concrete is not homogenous, so the bit could potentially skate if it happens to hit a pebble or an air pocket.
Always make sure that you are applying enough pressure to hold the drill in place, but don’t force it forward as this could potentially break the bit. As you get more practice, you’ll learn the proper amount of pressure to use.
From time to time – about every 10 to 20 seconds – you’ll want to pull the drill out slightly and push it back in again. This will help to pull the dust out of the hole. In addition, you’ll want to pull it out completely every now and then to allow the drill to cool. This is especially critical if you have a rotary drill since they are known to overheat when you are drilling for an extended period of time with them.
Since there are likely to be times that your dill is not going to go as deep as you might need it to or you may hit a hard piece of concrete, you’ll want to keep a masonry nail nearby to use. This will help to break up the concrete. Of course, you’ll want to avoid driving it so deeply that you can’t remove it. Once you remove the masonry nail, you’ll want to place the drill back into the hole and continue.
It’s important to note that if you start to see metal or sparks start shooting out, you’ve hit the rebar. At this point, you’ll want to stop drilling right away and switch out your bit for a rebar-cutting bit until you get past the obstruction.
Finally, blow out the dust once you have finished drilling your hole. Keep in mind that removing the dust will improve the strength of your concrete anchors. Be sure that you wear your goggles as you use compressed air or a squeeze bulb to blow out the dust. You can use your vacuum to clean up the debris.
