Applications

This holder is highly suitable for longitudinal turning and facing operations. It is particularly designed for roughing, where high material removal rates and strong cutting forces are present. The solid structure supports secure material removal during internal machining.

Special features

A key feature is the reliable claw clamping, which securely locks the indexable insert in its pocket. The tool holder system is available in various shank diameters ranging from 20 mm to 50 mm (S20R to S50V), offering the user flexible application possibilities on different machines.
