TPGH110302L-FS VP15TF
Mitsubishi Materials | PVD Coated "Miracles" Grade (Left-Hand)
Super-Finishing Overview
The Mitsubishi TPGH110302L-FS VP15TF is a precision-ground Left-Hand (L) PVD coated carbide insert engineered for super-finishing. Utilizing the advanced VP15TF Miracles grade, this tool provides excellent resistance to built-up edge (BUE) and thermal cracking. The FS chipbreaker is specialized for ultra-fine finishing at light depths of cut, making it a critical long-tail precision tool for CNC machining of stainless steel, carbon steel, and small-diameter boring applications.

VP15TF PVD Miracles
The VP15TF grade is a micro-grain carbide with an AlTiN PVD coating. This "Miracles" series is optimized for stable machining and superior tool life across diverse materials. It effectively prevents chemical wear during lathe turning of stainless steels and pre-hardened alloys.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-sharp rake and high positive geometry to minimize cutting forces. It provides excellent chip evacuation at extremely light feed rates, preventing surface damage in sensitive CNC boring operations.
