Drill cobalt fi 14,5 Inox

Drill 14,5 mm cobalt HSSE Inox. High-quality Inox cobalt twist drill bit with cylindrical shank manufactured according to the NWKa DIN 338 dimensional standard. It has 2 central blades and special chip grooves designed for fast chip removal up the hole. In addition, the drill has a blade angle of 118 degrees, and the holes made are axial along their entire length. Cylindrical drills in our store are characterized by very high cutting parameters, This is due to the use of a special HSSE high-speed steel with 5% cobalt in its production. Such a composition of the steel makes drill 14,5 cobalt resistant to very difficult cutting conditions, including, among other things, high temperatures (up to 670 degrees C) generated during high-speed drilling. The drills can be used to machine alloy steels, stainless steel, acid-resistant steel, heat-resistant and heat-resistant steel, as well as cast steel and cast iron. At the same time, the tools are characterized by high resistance to mechanical damage (breakage, cracking, chipping), which increases the period of their use. They are suitable for conventional drills, lathes, milling machines and computer numerical control machine tools.
