			There are many different models of cordless screwdriver, but most have the same basic parts:

			Integrated bit holder on a cordless screwdriver
			Most cordless screwdrivers have a bit holder integrated into the design of the chuck, which holds the screwdriver or drill bits.

			Cordless screwdriver chuck
			The chuck is the part that holds in place the detachable accessories such as screwdriver and drill bits or bit holders. Cordless screwdrivers come with either a quick-release chuck or a chuck with an integrated bit holder. For more information, see our section: What is the chuck?

			LED light on a cordless screwdriver
			Some power tools have a built-in LED light for working in poorly-lit spaces. The LED light is usually located above or below the chuck. For more information, see our section: What is the LED light?

			Torque control ring on a cordless screwdriver
			Torque is the turning force of the cordless screwdriver. It is this force that is used to drive screws or drill holes. Some cordless screwdrivers have a torque control ring which allows you to adjust the level of torque being delivered depending on the drilling or screw-driving task. For more information, see our section: What is torque?

			Cordless screwdriver battery-level indicator
			Some cordless screwdrivers have a battery-level indicator which tells you how much battery power the tool has left. For more information, see our section: What is the battery-level indicator?

			Gear selector switch on a cordless screwdriver
			Some cordless screwdrivers have more than one gear, meaning they can perform a wider variety of tasks. The gear selector switch allows you to alternate between gears, and therefore speed ranges. For more information, see our section: What is the gearbox?

			Cordless screwdriver motor
			Inside the body of the screwdriver is its motor, which is powered by the tool’s battery. The motor converts the battery’s electrical energy into mechanical energy giving the rotation required to turn the chuck. For more information, see our section: What does the motor do?

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

			Cordless screwdriver forward and reverse switch
			This switch allows you to alternate the direction in which the screwdriver or drill bit is turning. Forward is used for driving in screws and drilling, while reverse is used for removing screws and backing out drill bits. For more information, see our section: How to use reverse.

			Cordless screwdriver grip
			This is where the cordless screwdriver is held. Some models have a textured rubber grip and others just have contours in the plastic surface.

			Cordless screwdriver battery
			A cordless screwdriver is powered by a rechargeable battery and should come with a charger. Batteries are either detachable and can be removed from the screwdriver or come already built-in. There are three types of batteries: nickel-cadmium, nickel-metal hydride, and lithium-ion. For more information, see our section: What are the different battery materials?
