Applications

This turning tool is an effective solution for challenging internal machining and facing operations in general mechanical engineering and batch production. The focused coolant delivery is exceptionally beneficial when working with demanding materials or deep bores that require immediate chip clearance.

Special features

By directing the coolant flow straight to the cutting edge, the internal cooling channel actively helps mitigate thermal stress and supports steady tool life. In addition, the proven pin lock mechanism facilitates rapid and secure insert changes, contributing to streamlined workflows on the shop floor.
