Countersink

grabcad

A countersink is a tool used for creating a conical-shaped hole that allows screws to sit flush with the surface, providing an aesthetically pleasing finish and preventing the head of the screw from protruding. It can also be referred to as a counterbore or a pilot point. The process involves cutting a cone-shaped depression in the material, which allows the screw's head to sink into it. Countersinking is commonly used in woodworking, metalwork, and carpentry projects for a professional appearance.
