Quizplus · Accepted Answer

Countersinking is the process of cutting a tapered opening in a hole so that a flathead screw can be installed flush with the workpiece surface. Counterboring creates a flat-bottomed hole for a socket-head screw or a bolt head. Spotfacing involves creating a flat surface at the bottom of a hole. Reaming is used to improve the accuracy and finish of an existing hole.
