Advantages:
Geometry
- Special groove geometry for low-friction chip removal
- Designed for long-chipping materials
Coating/surface
- TiN (titanium nitride) coating to prevent the formation of built-up edges, inhibits the adhesion of material
- Coating ensures a smoother surface in the groove and in the thread profile
- Surface smoothing ensures reduced torque
Recommended applications
- Cutting speed vc = 10-20 m/min
- Use of cooling emulsion 6-8 %, or alternatively oil cooling
Area of application
- Steels up to 1000 N/mm²; structural and case-hardening steels, spheroidal graphite iron, black malleable iron
