VP15TF Miracle Coating
The VP15TF grade utilizes Mitsubishi's proprietary Miracle (Al,Ti)N PVD coating. This nano-layered coating provides superior resistance to adhesive wear and prevents Built-Up Edge (BUE). It is the premier choice for stainless steel turning, ensuring that fine profiles remain sharp and dimensionally stable throughout the production run.
F-Type Chipbreaker Logic
The F-type chipbreaker is engineered specifically for finishing. It features a narrow breaker width and a sharp cutting edge that manages chips efficiently even at exceptionally light depths of cut (under 0.5mm). This is essential for fine-finishing where chip bird-nesting could damage the surface finish of a delicate part.
