The modern handyman has plenty of mechanized tools in his arsenal, especially during our era where innovation plays an important key in maintaining relevance and achieving company targets when it comes to sales. Among these tools is the power drill and its accessories like the ratchet and drill bits, both of which can be expensive which may lead you to ask, "Are drill bits universal?"

It's a particular question, but these bits and pieces of metal play an important role in modern construction as its quality and strength can dictate how fast you can finish a project, as well as its overall quality. Handymen have a lot of tools in general, and they can be categorized depending on the specialty of the handyman, but the power drill would always be part of any kit regardless if the owner is focused on plumbing or electrical installations, even landscape artists have a place for this tool if you think of it.

Types of Power Drills

Power drills vary depending on its use and functionality, here are the basic power drill types:

  • Hammer Drill

This kind of power drill features a hammering function that lets you pound the drill bit as it rotates on the driver. It is ideal for tough materials like concrete and hardwood.

  • Rotary Drill

This kind of power drill is like an improved version of the hammer drill as it gives the same function, but it is powered by air pressure instead of electricity. This drive system allows it to have more impact and be made more tough and durable.

  • Impact Drill

This drill varies from driver drills through its ability to deliver rapid bursts of power which drives them deeper without running the risk of stripping the screw heads off. This is ideal for multi-screw jobs or if you need to fasten something over something.

  • Driver Drill

This is the more common type of power drill and is featured in most drill kits. This kind of drill can come in corded or cordless version; some manufacturers have created a hybrid that can function with or without an external power source.

Kinds of Drill Bits

So, back to the first question, "Are drill bits universal?" Before we tackle the answer to this straightforward question, it would be wise to know what are the different types of drill bits. Here are a few of them:

  • Twist Bit

The most common drilling bit that can be used on many materials including metal. This bit drills a straight hole and the indented spirals remove the debris as it drills deeper into the hole.

Twist bits come with several kinds of coating and materials, depending on the surface or material that you will be drilling a hole into.

  • Masonry Bit

This kind of drill bit is designed to handle brick, stone, and concrete, with most of the drill tips being made of tough tungsten carbide. Extreme care is needed when handling masonry bits as they can break off if overheating occurs.

  • Flatwood Bit

This kind of drill bit is used to drill larger holes in wood, usually sized for doorknob and deadbolt installations. This is unusually shaped as it's mostly flat, although it has a sharp point in the middle that acts as a guide whenever you would drill the initial holes in the wood.

  • Screwdriver Bits

Screwdriver bits are mostly used to drill pilot holes for secure installations and can be used to push down either flat head or Phillips-type screws. Twist bits and masonry bits can usually do this function with ease as well.

  • Tile Bit

Tile bits are made for drilling through ceramics and glass surfaces. It is also often used with some form of lubricant to help cool down the surface it is drilling. The tip of this drill is usually made of ground tungsten carbide.

  • Spur Point Bit

Also known as the dowel bit, spur points are used for drilling holes in timber, and it often leaves a clean, straight hole.

  • Countersink Bit

This kind of bit is used to form a conical recess on timber and plastic, although it has been known that it can be used with metal but only with careful direction and the right amount of experience. The most common use for this bit is for metal and concrete surfaces as it leaves a rough edge when used with wood or timber.

  • Augur Bit

Augur drill bits are just like twist bits, but they have a much larger flute and are mostly used for wood and softer materials like plastic. They are more adept to drilling deeper, straighter holes as the flutes make it easy to remove debris.

  • Step Drill

This drill bit is a little bit more expensive than the common drill bits as it is made with flexibility in mind. It looks like a step pyramid, but this design allows you to drill holes of varying sizes without having to change your drill bit. This is mostly used for thin materials like plastic and wood.

  • Hole Saws

Unlike the flatwood bits and twist bits, hole saws are a saw that is bent in a circle and has a central bit that serves as a guide as you drill into the material. The teeth of the saw are located around the diameter of the bit only which means it leaves the central part of the bit intact, making this ideal for drywall installations and joists.

Are Drill Bits Universal?

The answer to the question is that it depends on the drill bit that you have. Most drill bits released nowadays are universal, which means they can be used with any brand of a power drill, although one can still use older models of bits with different brands as long as the size of the drill bit fits that of the drill bit hole in the power drill.

Handymen can take on a lot of jobs, depending on the market that they are currently servicing, and it is better if they can use the same tool for this project and that without having to invest in another set when they cross specialties.

Power drills help save time and having universal drill bits not only saves time further, but it also saves money, increasing the income potential of any given project.
