Ø2.9 Inox cobalt drill bit for metal
2.9 mm cobalt drill bit for metal HSSE Inox. A professional drill manufactured from HSSE cobalt high-speed steel. This straight-shank twist drill complies with dimensional standard NWKa, DIN 338. It features 2 central cutting edges, special flutes for chip evacuation up the hole, and strong cutting edges resistant to impacts and lateral forces. The advantages of these drills result directly from their construction from high-speed steel with added cobalt. This steel composition improves machining productivity and accuracy (holes with low surface roughness). The drill cutting edges resist breakage, chipping, dulling, cracking and other types of mechanical damage. As a result, the drills can remain in service for a very long time without requiring replacement. These tools are designed for conventional drilling machines, milling machines, lathes and computer numerical control (CNC) machine tools. 2.9 mm cobalt drill bits for metal are recommended for all professionals.
