Features and benefits

RFDD Tips — High-performance roughing solution with excellent chip evacuation, especially in stainless steel.

The short design and corner radii provide stability and reduce deflection forces.

Ideally suited to perform long-reach applications on mill-turn machines, and driven tooling on lathes.

The unique cutting geometry results in low cutting forces, requiring low power consumption.

Grades

KCPM15

Coated carbide grade with thick PVD coating and optimized chemistry and process for increased wear resistance. Outstanding protection in milling stainless steel to mitigate crater, DOCN (depth-of-cut notching), and flank wear. Excellent performance up to 52 HRC.
