-
Size Matters
The most important thing is size. Drilling bits come in many sizes. These are measured in fractions of an inch or millimeters. You need the right size for the hole you need. Look for the size marked on the bit’s shank.

Shank Style
The shank is the part that goes into your drill. There are two main types:
- Round shanks: These work with most drills.
- Hex shanks: These are good for quick-change chucks.
-
Point Angle
The point angle is the angle of the tip. A common angle is 118 degrees. This works for most metals. Some bits have different angles for special jobs.
-
Flute Design
Flutes are the grooves on the bit. They help remove chips of metal. They also help cool the bit. Look for flutes that are well-designed.
