VP15TF Miracle Coating
The VP15TF grade is Mitsubishi's carbon-rich AlTiN PVD coating. This "Miracle Grade" substrate provides an incredibly tough edge that resists thermal cracking and built-up edge (BUE). It is designed to maintain stable cutting even in varying hardness levels of carbon steel and austenitic stainless steels.
Positive Chipbreaker Effect
The TCMT geometry features a 7° positive relief angle, significantly lowering cutting resistance. This indexable turning insert utilizes an optimized chipbreaker for medium-to-finishing passes, ensuring superior chip evacuation and preventing long stringy chips from marring the workpiece surface.
