Ø16.5 Inox cobalt drill bit for metal
16.5 mm cobalt drill bit for metal HSSE Inox. Advanced NWKa straight-shank twist drill bit for drilling through holes and blind holes with a diameter of 16.5 mm. The drill bits are made from special HSSE cobalt high-speed steel. This steel offers exceptional cutting properties. The addition of cobalt increases the durability and hardness of the cutting edges, making them more resistant to all types of mechanical damage (breakage, chipping, dulling). These features mean that 16.5 cobalt metal drill bits can remain in service considerably longer than tools made from conventional tool steel. The drills offered also provide higher cutting efficiency and greater achievable accuracy. The resulting holes have low surface roughness. These drills are recommended for professional work using conventional drilling machines, milling machines, lathes, and CNC machine tools.
