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.
