Ø0.5 Inox cobalt drill bit for metal
0.5 mm cobalt drill bit for metal HSSE Inox. Inox NWKa cobalt drill bit with a straight shank, compliant with DIN 338. Designed for drilling through holes and blind holes with a diameter of 0.5 mm. Made from advanced, high-grade HSS-E high-speed steel. The addition of cobalt (approximately 5%) improves the drill's cutting performance and increases its durability under very demanding operating conditions. In particular, the NWKa drills we offer enable machining of very hard and difficult-to-machine materials such as alloy steels, stainless steels, heat-resistant steels, acid-resistant steels, cast iron, and cast steel. In addition, straight-shank drills made from HSSE steel provide very accurate drilling and produce holes with low surface roughness. Our range of 0.5 cobalt drill bit for metal feature two ground central cutting edges and a 118° point angle. They are suitable for professional machining on drilling machines, milling machines, and lathes, as well as CNC machine tools.
