To anybody who’s not in-the-know, knowing the difference between 18V and 20V drill can be trivial and a little offputting to be discussing it over the Internet. Of course, anybody who works within the construction and house repair business knows that the differences matter, and it should be fair that it be discussed.

Hand drills are great tools to have in the workshop and construction site especially since they can make your life a whole lot easier when it comes to installing fixtures, aligning power lines, and assembling the different furnishings inside the house. These devices can create holes for you to place your bolts and screws in, as well as drill holes for your doorknobs and whatnot.

Kinds of Drills

All drills basically started from a manual version where the motor is powered by whatever you ate during lunch or breakfast, and the speed is just how fast you can rotate the crank in a minute. Motorized drills brought the drilling game to a whole new level as it made things more streamlined and efficient.

Discounting the larger drill types and sticking to handheld models, these drills can be classified into the following kinds:

  • Corded

This is your standard electric drill that powers its motor with an active electric current that comes right off the socket, through the plugs and cables.

  • Cordless

As the name says, this drill does not need any cord to run as it draws power from a battery pack that is attached at its base.

Uses for 18V and 20V Drills

Power drills have many uses both at home and elsewhere which makes it a justifiable expense in any related business. Most drill drivers would come with several attachments, and these can already be used in a variety of applications. Several other bits can be purchased at a small price to supplement and expand your arsenal of drill bits.


Hand drills were initially used for carpentry works as there was a need for carpenters to drill through the wood so that they can install fixtures and furnishings in their respective projects. Not only can you use cordless drills to install door knobs, but you can also use to create hinges and affix fixtures and ornaments to wooden material.


Manual hand drills cannot handle masonry, so it was only when the electric drill was introduced that masons started using electric power drills. This piece of equipment allows you to drill into concrete so that you can embed screws and affix steel and wooden support as well.

Having a well-drilled hole provides better support than having done it manually as the grip is tighter and better in comparison.

Electrical and Plumbing

Electricians would have more use for a cordless drill than plumbers as they get to install lighting fixtures and electrical outlets with it. Plumbers, on the other hand, use it to drill screw holes for shower heads and heaters, as well as sinks and other plumbing fixtures.

Difference Between 18V And 20V Drill

The 18V and the 20V Drills both fall under the classification of a cordless drill as the alphanumeric code refers to the power output of the battery packs that come with the cordless drivers. The difference between 18V and 20V drill though does not come from whatever is inside, but what is going on outside.

Upon closer inspection, these two power ratings have the same inner workings, the same components, and even the same number of batteries with the same voltage rating. Which begs the question, if these two are very similar why not consolidate them into one voltage rating. So what gives? And how can 18V/20V cordless drills benefit your business?

Benefits of using 18V/20V Cordless Drills

The cordless drill in itself already speaks of possibilities, but digging deeper, cordless drills can have the following benefits:

  • Portability

The absence of a power cord allows you to bring this drill driver almost anywhere that a job can dictate, be it atop an electric tower or down a tunnel where no light can pass through. The battery packs are replaceable which means you can use it while other packs are charging with a few more waiting to be locked and loaded.

  • Flexibility

As previously mentioned, you can take a cordless drill almost anywhere which means you can do a lot of things with it depending on the need of your project. Most drills would come with different drill bits that can be interchanged to suit the need that you have and being able to bring that kind of flexibility anywhere is a definite plus.

  • Less Mess

Aside from charging batteries, cordless drills don’t create messy octopus wiring and would not need its power line and extension for it to work.

The Composition of a Power Cell

These two popular battery packs look different on the outside to some but, if you would spare more than a few cents, deconstructing it would reveal a familiar sight. Taking apart each battery pack of an 18V drill and a 20V drill, you would see that each would have individual battery cells that are grouped by five and then wired in a series.

Each group of five would then be connected through a parallel arrangement. This particular battery alignment and series management allow and guarantee that the battery pack would have capacity when it comes to the number of watt-hours it can produce.

Typically, a cell can generate a nominal voltage rating of 3.6 Volts, multiply it by five in a parallel series equals about 18V of nominal rating. However, this also means that each cell has a maximum rating of four Volts which, when multiplied by five, is equivalent to 20V of maximum voltage rating.

Is There a Difference?

Looking at it, the 18V and the 20V battery packs that come with the cordless drills have no difference except in their labels, and possibly their appearance. So, it basically comes down to how manufacturers would want to market their products and apparently, having more power makes stuff more sellable.

If you would look closely on the label though, a 20V battery pack would have 20V Max which connotes that it is 20V Maximum. By extension, this means that both battery packs can generate the same amount of power and when choosing the right cordless drill for your business, either of the two will do.
