High-Performance Cermet Turning Insert for Finishing

The VBGT-SF indexable insert with the PVD-coated RTC+ cermet grade is specifically designed for the professional machining of steel and stainless steel. This positive turning insert opens up flexible application possibilities in both serial and individual production, where high dimensional accuracy and a clean surface finish are essential. Thanks to the special combination of substrate, coating, and chipbreaker, it creates good conditions for a reliable, continuous cut without chatter tendencies.

Applications

This cermet tool holder insert is excellently suited for fine turning operations in metalworking, particularly when unalloyed and alloyed steels as well as stainless steels need to be finished. It is predominantly used in external and internal machining tasks where a continuous chip flow and exact component contours are required.

Special features

The combination of a wear-resistant cermet base (ISO P05-P15) and a modern PVD coating ensures high thermal stability of the cutting edge. In conjunction with the SF geometry optimized for finishing, low cutting forces can be achieved, which reduces tool wear and noticeably promotes the surface quality of the machined workpieces.
