Like carbide burrs HM, with titanium-carbon-nitride coating. The TiCN wear protection coating increases the surface hardness of the tool to approx. 3,000 HV / micro hardness and the hot hardness resistance up to 400°C. This increases tool life and productivity. This increases tool life and productivity. Areas of application: for high-alloy, rust-resistant, acid-resistant and heat-resistant steels, cast iron and plastics. For deburring, edge breaking, fettling, weld seam processing and surface processing.
