Trapano a punta elicoidale HSS-G Co 5
The powerful, ground twist drills in accordance with DIN 338 type N are made of HSS (high-speed) steel with cobald alloy. The cobald content provides a higher thermosetting. The completely ground twist drills ensure an increased accuracy of concentricity.
The drills are suitable for unalloyed and alloyed steels up to a strength of 1,100 N/mm², hot and cold-work steels, tempered and case-hardening steels as well as corrosion and acid-resistant steels.
