Applications

This specialized internal turning tool is primarily focused on precise profiling within complex internal workpiece contours. The combination of the 95-degree cutting angle and a rigid claw clamping system enables professional users to achieve reliable machining even in hard-to-reach geometries. The exchangeable head is ideally suited for use on CNC lathes where consistent process reliability is required.

Special features

One of the defining features of this holder system is its comprehensive modular design. Instead of needing to prepare a complete monoblock boring bar for every machining diameter, replacing the compact tool head on the existing base bar is sufficient. The integrated claw clamping firmly secures the insert in place, contributing to a low-vibration machining process. This flexible concept strongly supports efficient workflows in both individual and series production environments.
