HB070

  • The steam tempered is a Fe3O4 oxide coating which reduces the friction between the tool and workpiece and prevents cold welding.

NB070

  • Recommended surface treatment for machining hard wear/abrasive materials such as grey cast iron, aluminum alloys with high silicon percentage (more than 10%).

PB070

  • The TiN coating has a hardness of approximately 2,300 HV and is temperature resistant up to approximately 600°C. This is an excellent golden colored coating for general applications.

GB070

  • TiCN takes place of TiN when the conditions require the coating to have a different hardness and toughness. The TiCN brings an advantage to machining very difficult steels or cutting interrupted bores. The TiCN-coating has a hardness of approx. 3,000 HV, but is temperature-resistant up to approx. 400° only. That means TiCN needs excellent cooling for long service life.

DB070

  • With its high wear resistance and slight adhesion on nonferrous metals DLC (Diamond-like carbon) coating is perfectly recommended for cutting Aluminium and Aluminium alloys.

AB070

  • This is a special coating for machining abrasive materials such as: gray cast iron, alu-alloys with silicon, fiber reinforced
    plastics, etc., or machining under high temperatures, which means with insufficient cooling, or high speeds ≥ 600m/min. The TiAIN has a hardness of approx. 3,000 HV and is temperature resistant up to approx. 800°.
