Features
- Stability & High Efficiency: The unequal flute spacing and 35/38° variable helix design effectively suppress vibration, allowing high-speed machining of steel and cast iron while significantly extending tool life.
- Versatile Geometry for Heavy Feed: An eccentric relief angle strengthens the cutting edge to support stable, high-feed rates. Optimized chip space and a center-cutting edge make it ideal for high-performance slotting and ramp milling.
Application
- Excel at working cast iron, carbon steels (~HB225), alloy steels (HB225~325), pre-hardened steels (up to HRC45), hardened Steels (HRC40~45), stainless steel.
FEATURES
Stable Machining, Unaffected by ImpuritiesEngineered for SCM440, bearing steel, and cast iron. The reinforced edge offers superior impact resistance, suppressing chipping in high-hardness or non-uniform metals to ensure a stable, long-lasting tool life.
Built for High-Speed MachiningThe helix angle ranging from 35/38° is an excellent anti-vibration effect, suitable for high-speed and high-efficiency machining of steel and cast iron.
Reduced Vibration Longer LifeUnequal flute spacing design can reduce the vibration and prolong life.
