Metal drill bit СПЕЦИАЛ/Special HSS-G 3.5x70/35mm (pkg.10pcs) Cutop 54-944

HSS-G Cutop Special metal drill bit is used for drilling through and blind holes in metal workpieces (alloy and carbon steel, gray and malleable cast iron, non-ferrous metal, and plastic). The 135° point angle, A1 precision class, and long spiral design of the drill 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 hole wall processing. Laser marking of the size and material of the drill facilitates quick identification.
