Feature:
Save time changing between countersink and screw bits with the quick-change Centrotec System
Reduce fatigue with the lightweight Centrotec chuck and decrease drilling/driving clearance with the compact design

A countersink bits 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 hex-headed capscrew. ) a countersink may also be used to remove the burr left from a drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges.
