Ø9.9 Inox cobalt drill bit for metal
Professional extra-long drill 9.9 mm cobalt metal drill bit Inox straight shank twist drill manufactured to dimensional standard NWKa, DIN 338. This solid drill is made entirely from modern cobalt high-speed steel HSS-E. This exceptional tool steel, combined with the drill's design, provides high resistance to demanding cutting conditions and improved precision (the resulting holes have low surface roughness). In addition, cobalt drills are significantly more resistant to all types of mechanical damage occurring when machining difficult-to-cut materials. They very rarely suffer breakage, cracking, edge fracture, or chipping. The cutting lips are ground, and the strong cutting edges withstand heavy impacts and lateral forces. Designed for conventional drilling machines and computer-controlled CNC machine tools. 9.9 mm cobalt metal drill bits, are suitable for drilling holes in sheet metal, alloy steels, stainless steel, heat-resistant steel, acid-resistant steel, cast steel, and cast iron.
