How Does Cordless Electric Drill Work?

If you’re a DIY enthusiast or a professional, a cordless electric drill is a must-have tool for your toolkit. It’s one of the most versatile and commonly used power tools, and it can help you accomplish a wide range of tasks around your home or workplace.

In this article, we'll dive into the inner workings of cordless electric drills to help you understand how they work and what makes them an essential tool for any project.

Power source.

Unlike a corded drill, a cordless drill runs on a rechargeable battery, usually lithium-ion. The battery is what gives the drill its power to turn the drill bit and perform tasks like drilling, driving screws, and so on. The battery's voltage level determines the tool's power, with 18V being the most common voltage level for cordless drills.

Motor.

The motor is the heart of the drill. When you press the trigger, it activates an electric switch that sends power from the battery to the drill's motor. The motor then sends the power to the chuck to turn the drill bit.

Chuck.

The chuck is the part of the drill that holds the drill bit. Most cordless drills come with a three-jaw chuck that can hold a wide range of bit sizes and shapes. To change a bit, you need to loosen the chuck by rotating it counterclockwise. Once the chuck is loose, you can remove the old bit and install a new one by inserting it into the chuck and tightening it by rotating it clockwise.

Clutch.

The clutch is a feature that helps prevent the drill bit from overloading and breaking or stripping screws. It's like a torque limiter that helps you apply the right amount of force without damaging the material you're working on. Cordless drills usually have a dial that you can turn to adjust the clutch setting to match the task you're working on.

Speed control.

Cordless drills come with speed control features that allow you to adjust the speed of the drill bit. The speed setting is usually controlled by a button or a dial located near the trigger. Higher speeds are ideal for drilling through hard materials like metal, while lower speeds are suitable for softer materials like wood.

Conclusion.

Cordless electric drills are versatile, powerful, and easy to use. They offer the convenience of being able to work without a power cord, and their rechargeable batteries make them easy to maintain. In summary, the components that make cordless drills work are the battery, motor, chuck, clutch, and speed control.
