Countersinking – creating a recess

Countersinking means creating a recess by using a mechanical machining operation in a hole that has been drilled. The purpose of this machining operation is to countersink a screw into the drilled material so it no longer protrudes above the surface of the material. The machining operation which achieves this is called "countersinking".
