Drill cobalt fi 0,8 Inox
Drill 0,8 mm cobalt HSSE Inox. Professional cobalt Inox drill bit, for making through-holes and blind holes with a diameter of 0.8 mm. This drill is recommended for machining very hard and hard-to-machine materials such as alloy steels, stainless steels, acid-resistant steels, heat-resistant steels, cast iron, cast steel and non-ferrous metals. The cylindrical drills offered in our store are manufactured entirely from modern HSSE high-speed steel. This is a high-grade tool steel with 5% cobalt, the properties of which contribute to better drilling results. First of all, they are resistant to high temperatures (as high as 670 degrees C) created when drilling at high speed. Thus, drill 0.8cobalt NWKa allow high-speed machining and reduced working time. In addition, they are resistant to mechanical damage caused during machining, thus reducing labor costs. The drills are recommended for conventional drilling machines, as well as for lathes, milling machines and CNC numerical control machine tools.
