Grade Description

This grade is your first choice for case and induction hardened steels. With its medium content of boron nitride, it is suitable for light to medium interrupted cuts.
Suitable for processing: HRC40-65 high hardness steel, quenched steel, gear steel, tool steel, bearing steel, mold steel, high-speed steel, etc., with both collapse resistance and wear resistance.
Benefits
- Longer and more stable and consistent tool life
- Efficient and secure machining with good surface finish
- Consistent dimensional tolerances
- Lower cost per part when aiming for a one-cut strategy at high speed
- Improved wear resistance
