Ø15.5 Inox cobalt drill bit for metal
15.5 mm cobalt drill bit for metal HSSE Inox. High-grade straight-shank twist drill bit with a diameter of 15.5 mm. Our straight-shank drill bits feature two central cutting edges and specially ground cutting edges that withstand impacts and lateral forces. The drill bits also offer exceptional cutting performance. Their cutting edges withstand demanding operating conditions and resist breakage, cracking, chipping, and other mechanical damage. These advantages result from the use of special HSSE cobalt high-speed steel to manufacture the drill bits. This advanced tool steel increases cutting efficiency, reducing machining time and improving the utilization of existing machine tools. In addition 15.5 cobalt drill bit for metal enable more accurate machining, and the resulting holes have low surface roughness. The tools conform to the NWKa, DIN 338 dimensional standard. Suitable for conventional drilling machines, milling machines, lathes, and computer numerically controlled CNC machine tools.
