### How do you write countersink?

How do you call chamfers?

If a chamfer is called out as a face width, then it is to be measured along the hypotenuse of the chamfer. To convert a leg length dimension to face width simply multiply the leg length value by 1.414. To convert from a face width dimension to a leg length dimension, reverse the process and divide by 1.414.

How do you write counterbore?

A counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature.

#### What is the difference between a spotface and counterbore?

What is a chamfer bit?

Chamfer bits are used to cut a beveled edge on the profile. They can also be used to create angled edges for constructing boxes. For a 4-sided box, use a 45 degree chamfer bit.
