Metal drill bit SPECIAL/Special HSS-G 4.8x86/46mm (pack 2pcs) Cutop 54-974

HSS-G Cutop Special metal drill bits are used for making through and blind holes in metal workpieces: alloy and carbon steel, gray and malleable cast iron, non-ferrous metal and plastic. A 135-degree grinding angle, A1 accuracy class, and a long spiral drill design ensure fast, stable drilling. HSS-G drills have increased hardness due to full grinding of the cutting surface with boron nitride. This ensures high quality of hole wall processing. Laser marking of the drill size and material facilitates quick identification.
