Machine tap drill M DIN 371 HSSE-Co 5 VAP, ground

Machine taps from cobalt-alloyed and vaporized high-performance high-speed work steel. For through thread and blind hole thread, in unalloyed and alloyed steels up to 1000 N/mm² strength, VA metals. The thread is cut in one operation. "Vaporization" refers to the evaporation of a non-metallic oxide layer. Vaporization acts as a barrier and reduces the formation of cold weld-on. Cold welding is a workpiece chip that is welded on the edge of the tap and damages the manufactured thread. The consequences of cold welding are cracked and unclean thread flanks. VAP improves the adhesion of lubricants to the tool surface.
