Bit

The piece of metal that goes into the drill's tip. There are bits for drilling holes and bits for driving screws.

Black oxide bits

High Speed Steel Drill Bits with a Black Oxide finish which is created by a combination of chemicals and heat during the manufacturing process. Because of this finish, they have a higher resistance of rust and stay sharper longer; for use in general purpose drilling

Brad-point bit

A bit with 3 small points at the tip. Prevents the bit from "walking" when you start drilling. For precise drilling and for wood only.

Bubble Level

The water tube on the top and back of the drill that shows you when you are level with your drilling surface.

Chuck

Chuck Jaws

The portion at the very tip of the drill that holds the bit in place.

Chuck Key

An additional tool required to loosen and tighten the chuck.

Clutch

The ring around the front of the drill (usually right behind the chuck) that lets you adjust the torque setting.

Clutch out

When the material you're driving into is too dense or tough for the clutch setting, the drill will stop moving the fastener. This is designed to protect your surface from damage. Adjust the clutch to a higher setting to complete the drive.

Countersink

A bit that creates a pocket for the screw or fastener to fit in and be flush with the top of the material. The size of the pocket should match the size of the screw head. High Speed Steel countersinks can also be used to clean the edges of holes in metal and plastic.

Pocket Hole

A hole is made for driving screws at an angle. Commonly used for furniture

Pocket hole jig

Shank

The section of the bit that goes into the drill's chuck. The most typical shanks are round, 3-flat, reduced and hex shaped.

Sink

To drive a fastener into material.

Spade bit / Paddle bit

Tapered head wood-screws

A common type of fastener used for wood work.

Tile Bits / Glass Cutting Bits

Drill bits with a triangular carbide tip or tips used to drill holes in glass and tile.

Titanium coated drill bits

High Speed Steel Drill Bits with a Titanium Nitride coating which helps the drill bit stay cooler when in use, especially when drilling metal. This helps the drill bit stay sharper longer. For general purpose drilling

Torque

A drill's word for power. High torque means the drill/driver is turning the bit very hard.
