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. For more information, please see the page What are the different battery materials?

 
     
   

Cordless drill driver grip

 
 Grip of a cordless drill driver 

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

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

 
 Forwards/reverse button on a cordless drill driver 

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 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.

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.
