Applications

Thanks to the special solid carbide design, this tool holder is a practical choice for demanding internal machining tasks. It demonstrates its strengths particularly when long projection lengths are required. The stable construction supports low-vibration turning, allowing precise contouring to be implemented reliably in mechanical engineering and series production.

Special features

The solid carbide boring bar significantly reduces occurring vibrations and allows a projection length of up to 6xD. This characteristic creates very good conditions for improved surface quality and increased dimensional accuracy on the workpiece. The internal cooling channels direct the coolant straight to the cutting zone, which facilitates chip evacuation during internal machining and promotes constant temperature conditions.
