Innovative clamping system ensures stability in parting-off operations

4 types of inserts are available for various parting-off diameters and can be mounted in the same pocket of the toolholder.

Toolholder for sub-spindle

- Perfect for parting-off a short workpiece in a narrow approach

when a sub-spindle is used.

- Optimized overhang length for stable machining

- The unused cutting edge is always protected due to the innovative clamping system.

- Even if the first cutting edge is chipped, the other unused cutting edge can be used because the insert is clamped in the center.

Unique clamping system for highly rigid clamping

SH725, new PVD grade for small lathes

- PVD grade designed for precision part machining

- Good balance between hardness and sharpness

- High adhesion strength

Delivers stable machining on small lathes

DuoJust-Cut doubles tool life and provides excellent surface fi nish due to highly rigid insert clamping.

Chip control of DuoJust-Cut is better than the competitor’s even in parting-off of thin workpiece. Also, the DuoJust-Cut insert with sharp cutting edge provides stable machining without chattering.

DuoJust-Cut extends tool life up to 130% and reduces burrs due to the sharp cutting edge.
