Ø4.3 Inox cobalt drill bit for metal
4.3 mm cobalt drill bit for metal HSSE Inox. A high-quality twist drill for professional applications. It features a plain straight shank, special flutes for chip evacuation up the hole, and strong cutting edges resistant to impacts and lateral forces. The drill is manufactured from modern HSS-E high-speed steel. This cobalt steel provides significantly higher cutting performance than drills made from conventional tool steel. The drills we offer exhibit very high hardness and wear resistance, even at very high temperatures. Their cutting edges resist breakage, cracking, chipping and other damage. This makes them suitable for machining alloy steels, stainless steel, heat- and acid-resistant steels, as well as cast steel and cast iron. 4.3 mm cobalt drill bit for metal is recommended for conventional and CNC machine tools.
