What are the parts of a cordless drill driver?

There are many different models of cordless drill driver, but most have the same basic parts.

Cordless Drill Driver Battery

Cordless drill drivers are powered by a rechargeable battery and should come with a charger. On most models, the battery is detachable and can be removed from the tool when it comes time to recharge it.


There are three types of batteries: nickel-cadmium, nickel-metal hydride, and lithium-ion.

Cordless Drill Driver Grip

This is where the cordless drill driver is held. Some drills have a textured rubber grip, others just have contours in the casing’s plastic surface.


A textured rubber handle offers more grip in moist conditions and makes the drill driver more comfortable to hold for longer periods.

Cordless Drill Driver Speed Control Trigger

The cordless drill driver is operated using the speed control trigger. Pulling the trigger starts the chuck turning. The further you pull it in, the faster it will go, and to slow down or stop, you simply release the trigger.

Cordless Drill Driver LED Light

Some cordless drill drivers have an LED light for working in poorly-lit spaces. The LED light can be located underneath, on top of, or actually on the chuck and should turn on automatically when the speed control trigger is pulled.

Cordless Drill Driver Forward and Reverse Button

This button allows you to alternate the direction in which the drill driver turns the drill or screwdriver bit. Forward is used for driving in screws and drilling, while the reverse is used for removing screws and backing out drill bits.


This button is usually located just above the trigger, so you can reach it easily using your thumb or forefinger.

Cordless Drill Driver Chuck

The chuck is the part that holds in place the detachable accessories such as drill or screwdriver bits. All cordless drill drivers have a 3-jawed chuck.

Cordless Drill Driver Torque Control

Torque is the turning force of the drill driver. Most cordless drill drivers have torque control, which allows you to regulate this turning force.


How much torque you need will depend on the size of the screw you want to insert, the diameter of the hole you want to drill and the kind of material you are working with.

Cordless Drill Driver Selector Switch

Some cordless drill drivers have several gears and therefore speed ranges, meaning they can perform a wider variety of tasks. The gear selector switch allows you to alternate between gears.

Cordless Drill Driver Motor

Inside the body of the drill driver is its motor, which is powered by the rechargeable battery. The motor converts the battery’s electrical energy into mechanical energy giving the rotation required to turn the chuck.
