Applications

This internal tool holder is specifically designed for internal metal cutting where complex contours and precise profiles are required. The 107.5-degree cutting angle facilitates plunging and shaping operations inside bores. The tool holder is suitable for CNC turning centers as well as conventional lathes and supports cost-effective machining with DC inserts.

Special features

The boring bar stands out due to its uncompromising mechanical stability. The direct screw clamping minimizes interfering contours and guarantees a quick insert change. With variants starting from a 12 mm shank diameter and for minimum bore diameters from 16 mm, the tooling system can be flexibly adapted to different workpiece sizes.
