What is Countersinking?

Countersinking is a process that creates a V-shaped edge near the surface of a hole. It is often used to deburr a drilled or tapped hole, or to allow the head of a countersunk-head screw to sit flush or below a surface. Chamfering endmills are commonly used to make countersinks when CNC milling. When made using a drill press or lathe, a tool appropriately called a countersink is used. Countersinks can be made to almost any angle, but are commonly between 60° and 120°, with the most common being 82° and 90°.
