0.4 mm cobalt drill bit for metal HSSE Inox. High-quality Inox cobalt drill bit manufactured to the NWKa DIN 338 dimensional standard. It features 2 central cutting edges and flutes that efficiently evacuate chips up the hole. These straight-shank drills have a 118° point angle and can drill holes that remain on-axis throughout their full length. A distinctive feature of the drills we offer is their construction from special HSSE cobalt high-speed steel. The addition of cobalt makes the drills resistant to demanding operating conditions, including high-speed drilling that generates high temperatures. 0.4 cobalt drill bit for metal with cobalt withstand temperatures as high as 670°C. Thanks to their properties, the drills can be used to machine alloy steels, cast iron, cast steel, stainless steels, and heat-resistant steels. They are recommended for conventional drilling machines, milling machines, and lathes, as well as CNC machine tools.
