In this article, you'll be learning about cordless drill basics:
Chuck: This is the adjustable part of the drill that holds the drill bit.
- Picture a hand with the fingers open wide, then closing to grab something. That’s what the chuck does. It grabs the bit, holds it in place and lets it rotate.
- Some chucks require a special key to change drill bits. Most don’t need any extra tools to swap bits, as you can twist them open by hand.
Clutch or torque selector: This selector adjusts to increase or decrease the drill’s speed.
- Go with higher speeds for drilling.
- Stick with lower speeds for driving a screw.
Trigger: You squeeze this piece to operate the drill. It’s a standard trigger that you pull with your finger. When you release the trigger, the drill bit stops rotating.
Battery: This is the power source for your drill.
Bit holder on a drill: Spot to storage the bit.
