Countersink / Counterbore holes

 Countersink holes V.S. Counterbore holes

 

A countersink is a conical hole cut into a manufactured object, or the cutter used to cut such a hole. A common use is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material. By comparison, a counterbore makes a flat-bottomed hole that might be used with a socket-head capscrew.
