Ø8.3 Inox cobalt drill bit for metal
8.3 mm cobalt drill bit for metal HSSE Inox. Twist drill bit with a smooth straight shank for drilling through holes and blind holes with a diameter of 8.3 mm. The drill bits are manufactured to the NWKa, DIN 338 dimensional standard from special HSSE cobalt high-speed steel. The main advantages of our drill bits are high drilling efficiency, high accuracy, and resistance to very demanding machining conditions. The drill bits can be used to drill holes in components made from very hard alloy steels, stainless steel, acid-resistant steel, heat-resistant steel, cast steel, cast iron, and nonferrous metals. Drilling at very high speeds is possible because the drill cutting edges withstand high temperatures of up to 670°C. Compared with tools made from conventional tool steel, these HSSE steel drill bits are much stronger, ensure a long service life, and enable more accurate machining under demanding conditions. 8.3 mm cobalt drill bit for metal is recommended not only for conventional drilling machines, lathes, and milling machines, but also for professional CNC machine tools.
