Ø4.1 Inox cobalt drill bit for metal
4.1 mm cobalt drill bit for metal HSSE Inox. A professional twist drill with a plain straight shank for drilling through and blind holes with a diameter of 4.1 mm. It is manufactured in accordance with the Polish dimensional standard NWKa and its counterpart DIN 338 from modern HSSE high-speed steel. Straight-shank drills made from this specialized tool steel are intended for large manufacturing facilities for professional drilling in very hard and difficult-to-machine materials. These include alloy steels, acid-resistant steel, heat-resistant steel, stainless steel, nonferrous metals, gray and ductile cast iron, as well as cast steel. The ability to cut such hard materials results directly from the high cutting performance of HSSE steel. It enables highly productive and very accurate drilling. In addition, the drills offered withstand the very high temperatures generated during high-speed drilling, as well as possible thermal shocks. Furthermore cobalt drill bits for metal, 4.1 mm are resistant to all types of mechanical damage, such as breakage, cracking, chipping and others.
