What is an 18V Drill and What is it Used For?
An 18V drill is a popular power tool that’s used to drive screws and drill holes. It is, arguably, the most useful tool for professionals and DIY enthusiasts. They’re ideal for nearly every type of driving and drilling tasks, except for very heavy-duty jobs.
Since an 18V drill can be used to fix fasteners and screws onto surfaces or drill holes into walls, wood, and other tough surfaces, it’s perfect for woodworking and furniture assembly. The drill may also double as a saw, allowing you to cut out holes for sink faucets, drains, and doorknobs. The hole saw-bits are available in several different sizes and can be attached to the drill, enabling the tool to cut out a flawless round circle.
What is a 20V Drill and What is it Used For?
One of the most versatile items in a carpenter’s toolbox, a 20V drill significantly reduces the labor required to complete several projects. This well-rounded tool is suitable for DIY projects, minor home repairs, and even professional worksites.
With the right 20V unit, you can drill through sheet metal, lumber, concrete, and more. The tool is also used by construction workers and drywall installers because of its long-lasting batteries and ease of use. To put it simply, a 20V drill is the perfect handyman’s tool.
Similarities and Differences
When it comes to cordless power tools and deciding between 18V and 20V batteries, a lot of people get confused quickly. Although the latter seems to pack a lot more power, it’s important to note that the former is just as powerful.
To help you make an informed decision about which type best fulfills your specific needs, we’ve compared the two in detail, highlighting their similarities and differences:
18V and 20V Drill Similarities
In order to properly understand the design and mechanics of the two batteries, you’ll need to take a closer look at their components. Upon doing so, you’ll realize that they have some similarities, such as:
Construction
Both can be classified as cordless drills. If you look closely, you’ll see that both types are designed with the same components, the same inner mechanisms, and the same number of batteries. In fact, the batteries also have the same voltage rating.
Design
The batteries of these two drills have an incredibly similar design. Both feature individual battery cells that are aligned in a group of five and are wired in a single series. Each group is further connected in a parallel arrangement with a wire. This specific design increases the number of amp hours of the battery and ensures a good capacity of watt-hours.
This makes it clear that both batteries basically deliver the same amount of power. It’s important to emphasize that the batteries and motors are the same on a base level, and 20V and 18V drills are essentially the same thing.
What is the Difference Between an 18V and 20V Drill?
The drills themselves don’t have any significant differences, but the cells in them differ in the following ways:
Voltage Ratings
A closer look at the battery cells shows that every cell has two voltage ratings, namely maximum and nominal. Each cell in a 20V and 18V battery features a nominal voltage rating of 3.6V, which totals to 18 volts nominal if put together. Similarly, each cell in a 20V and 18V battery has a maximum voltage rating of 4V, which totals to 20 volts if put together.
Basically, manufacturers of 20V batteries use the maximum rating, while the manufacturers of 18V batteries use the nominal rating. This is the main difference between the two drills.
Availability
Another major difference between the two products is that 20V batteries are commonly sold in the US, while 18V batteries are available for purchase outside the United States. However, it’s important to remember that a person using an 18V battery outside the United States will get the same results as a person using a 20V battery within the US.
Also note that some drills are designed to work only with 18V batteries, while some models are designed to work only with 20V batteries.
Top Pick Between 18V and 20V Drill
As explained above, there’s no real difference between an 18V and a 20V drill. However, there are some significant differences you’ll have to consider before you take your pick. To ensure you don’t end up wasting your money, it’s advisable to take a look at the following features:
Weight and Size
Make sure you consider the weight and size of the drill before you finalize your purchase. A 20V drill is usually quite heavy and might cause problems in the middle of your project. Along with getting tired of constantly holding the drill in place, you’re also likely to wear yourself down by moving it from one area to another.
In regards to the size, it all comes down to what you’re planning on using the drill for. If you’re going to use the drill in narrow areas, then it’s better to buy a compact model. However, if you work in large spaces, then you can choose a unit of any size, as long as it meets your expectations.
Usability
The usability of a drill is what makes it exceptional. Quality models are designed with sound notifications and light indicators, making them incredibly easy to use. Different colored lights inform users of the current settings and the amount of power available. Thus, it’s advisable to choose an 18V drill that’s designed with such features rather than a 20V model without them.
Torque
It’s important that you choose a unit that offers the maximum torque. If a 20V drill offers higher torque than an 18V model, then you should go for it and vice versa. This is because a higher torque will lead to better results, especially if you’re going to use the drill on hard surfaces.

Aspects to Consider Before Buying a Drill
The right model can tighten or loosen screws, chisel away materials, and bore holes. To help you make the right decision, we’ve listed some of the aspects you should consider before buying a drill:
Speed
Measured in RPM (revolutions per minute), the speed of a drill tells you how fast it rotates. It’s better to choose a model that enables you to change the torque and speed according to the task or material you’re drilling into. A lower speed is suitable for driving screws and drilling into soft materials like wood, while a higher speed is ideal for drilling into hard materials, like stone.
Auxiliary Handle
An auxiliary handle enhances accuracy and safety while drilling. You can position the additional handle on the right or left side of the unit, which would lead to increased control over the drill.
Accessories
To make your work easier, you should choose drills that work with several different accessories. Such models will enable you to finish your projects with exceptional accuracy and within a short amount of time.
Variable Clutch Setting
A variable clutch setting allows users to adjust the torque, which is a twisting source that overcomes resistance and enables you to screw to the right depth. If you choose too much torque, you’ll drive the screw in too deeply, which can lead to a loss of accuracy and control and damage the workspace.
Conclusion
All in all, there’s no actual difference between a 20V and 18V drill except in place of use and voltage ratings. It’s important to remember that ultimately, no matter what you choose, you’ll get the same amount of power. Thus, it’s better to focus on the different features a drill has to offer instead of just relying on the indicated voltage.
