Grooving and parting-off tool series with optimally rigid self-clamping system

Highly rigid self-clamping system improves productivity for deep grooving and parting-off operations

Applications & Features

External groovingInternal groovingParting-oCoolant hole

Unique, high rigidity self-clamping system

1. The stopper supporting the insert bottom ensures secure edge position for excellent repeatability
2. The pocket is designed to securely spring-clamp the insert with three contact faces for stability
3. Smooth uninterrupted chip flow is possible thanks to two variations of effective 3D chipbreakers
