Spot drilling/chamfering tool C-CENTERING

Centre drills
C-Centering Cutter
The C-Centering Cutter is a multifunction cutter capable of both spot drilling and chamfering. The coolant hole allows cooling of the cutting edge, which reaches high temperatures during spot drilling in particular, and enables immediate chip evacuation.
During spot drilling, the insert nose radius can be easily chipped with general cutters since the center has a peripheral speed of zero. At the nose radius on the C-Centering Cutter insert forms negative land, it has high chipping resistance and the tool life is significantly extended.
