Countersinks

A countersink drill bit, typically used for installing screws, is a specialized type of drill bit used to create a conical hole. The design of the countersink drill bit allows it to create a hole that is wider at the top than at the bottom. This enables the head of the screw or bolt to sit flush with the surface of the material.
