What Is a Countersink?

The term "countersink" has two main definitions in the industrial world. The first definition of countersink is a hole that is conical in shape and is cut into a workpiece or manufactured object. The second definition of countersink is the tool used to cut the aforementioned kind of hole, such as a countersink bit or drill bit with countersink.

What Are Countersinks for?

The main purpose of any countersink bit is to cut a clean, angled hole into a piece of material in order to allow some sort of fastener, such as a bolt or screw or rivet, to be placed into the hole and sit flush with the surface of the material, rather than sticking out at the top.

Countersink bits can also be used to get rid of any excess material inside a pre-existing hole, like burrs left over from drilling, making the hole cleaner and neater for screws and other fasteners to be put into.

Countersinks have a lot in common with counterbores, but with one key difference: while countersinks create angled, tapered holes that gradually become narrower at the bottom, counterbores simply create straight, flat-bottomed holes instead.
