Features

1. High-Rigidity Geometry for Hardened Steel Machining: The combination of a small helix angle, specialized flute geometry, and increased core thickness delivers maximum tool rigidity, ensuring superior drilling performance in high-hardness steels above HRC45.
2. Negative Rake Angle for Maximum Chipping Resistance: Features an innovative negative angle design that reinforces the cutting edge, effectively protecting it against chipping during demanding operations to ensure extended tool life and reliability.

Application

• Excel at working carbon steels (~HB225), alloy steels (HB225~325), pre-hardened steels (up to HRC45), hardened Steels (HRC~55), high-hardened Steels (~HRC65).
