VP15TF Miracle Grade Technology
VP15TF is Mitsubishi’s proprietary PVD coated grade. It features a micro-grain carbide substrate for high toughness and a smooth coating that prevents built-up edge (BUE). It is designed for stable turning across diverse materials, offering long tool life even in stainless steel turning applications.
F-Breaker Geometry
The F-breaker (Finishing) is a precision-ground chipbreaker designed for light depths of cut. It ensures superior chip evacuation and minimizes cutting force, making this indexable turning insert ideal for thin-walled parts and high-surface-finish requirements.
