The drill is a great tool for any homeowner to consider acquiring. You can use them for anything from hanging up a picture to redoing your home.

But, if you are new to the world of drills, they might be a little bit intimidating. That is why today we will be looking at all of the main parts of this versatile tool, and explaining what they do and how they are used. Read on!

1. Power Source

Naturally, every drill will have a power source. They might be powered either by a cord, or battery pack. In either case, the power source will typically be located on the butt of the grip.

2. Chuck

The chuck is where you insert and fasten your drill bit. In days gone by, they used to require a tool, called a “key” to secure the bit.

You’ll still see chuck keys occasionally, but newer technology has come close to making them extinct. Contemporary chucks can usually receive bits without the help of any tool.

3. Trigger

The trigger is what will activate the drill. It’s located towards the top of the handle in a location similar to that which you’d find on a toy gun.

Some drills feature a variable speed trigger. This feature will allow you to control how fast the bit spins by how hard you squeeze it. It’s a great feature for tackling a wide range of projects, but simpler drills often won’t be capable of doing it.

4. Reverse Switch

Your drill will also feature a switch near the trigger that controls if the bit spins forward or in reverse. You will use the forward feature for drilling into a workpiece, and the reverse switch for when you are extracting materials.

This is mostly used in accordance with screws.

5. The Drill Shaft

The drill shaft is where the motor is located. It is also the region of the tool that serves as a bridge between the chuck and the trigger.

6. The Drill Bit

The drill bit is not technically a part of the drill itself, but the tool is also pretty useless without them. Bits come in a wide range of shapes and sizes. They are fastened into the chuck with the purpose of making holes.

There are drill bits out there that are made with a variety of purposes in mind, including drilling in metal, wood, plastic, and even bricks and concrete.


As you can see, the drill isn’t quite so intimidating as it might first appear. Though there are lots of different parts to this versatile tool, they are actually very easy to work with.

Now that you have a rudimentary understanding of the drill and all of its parts, you should have no trouble using yours to complete a wide range of do it yourself projects around the house.
