Highly rigid “Double-Clamp” system

Highly rigid “Double-Clamp” system provides remarkable stability and high accuracy

Applications & Features

Internal turningExternal turning

1. Simple and strong double-clamp system

– Provides strong clamping force with one screw.
– Only one screw and one action delivers double clamping force by simultaneously pushing down and pulling. This strong clamping force provides high stability for the cutting edge.

2. Higher indexing accuracy

3. Unique clamp improves rigidity

Larger holding area enhances clamping force drastically. Higher rigidity provides excellent stability and reduces vibration.
