Drill cobalt fi 10,5 Inox

Drill 10,5 mm cobalt HSSE Inox. Professional cobalt Inox cylindrical twist drill bit made according to the NWKa, DIN 338 dimensional standard from special cobalt HSSE high-speed steel. The content of about 5% cobalt in the composition of the steel influences a noticeable increase in the cutting properties of the drill bits. First of all, they are more resistant to possible mechanical damage when drilling very hard and hard-to-machine materials. In addition, drill 10.5 cobalt steel NWKa allows high-performance and highly accurate drilling. The holes produced are axial along the entire length and are of low roughness. They are designed for drilling holes in parts made of alloy steel, stainless steel, acid-resistant steel, heat-resistant steel, cast iron and cast steel. They can be drilled at high speeds, during which very high temperatures are generated - up to 670 degrees C.
