Coutersink VP, made of M2 HSS. Their 82° point angle is ideal for countersinking and they can also be used for deburring and chamfering in steel, stainless steel and non-ferrous metals. Variable pitch design allows chatter free countersinking for a clean finish. The special surface treatment increases cutting edge hardness and reduces frictional heat to extend tool life. The special tip geometry centers the tool in the hole to produce a uniform chamfer.
