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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
