TPGH090202L-FS VP15TF
Mitsubishi Materials | PVD Coated "Miracles" Grade (Left-Hand)
The Mitsubishi TPGH090202L-FS VP15TF is a high-precision Left-Hand (L) PVD coated carbide insert engineered for super-finishing. Utilizing the legendary VP15TF Miracles grade, it offers an exceptional balance of wear resistance and edge toughness. The FS chipbreaker is designed for ultra-fine finishing at light depths of cut, making this a critical long-tail precision tool for CNC machining of stainless steel, alloy steel, and exotic materials.

VP15TF PVD Carbide
The VP15TF grade is a micro-grain carbide coated with AlTiN. This "Miracles" coating provides incredible heat resistance and prevents built-up edge (BUE). It is specifically engineered for lathe turning operations that require stable machining across carbon steels, stainless steels, and cast iron.
FS "Super-Finish" Breaker
The FS chipbreaker features an ultra-sharp cutting edge and high positive geometry. It provides superior chip evacuation even at the lightest depths of cut, ensuring a clean workpiece surface and preventing the stringy chips common in CNC boring of stainless materials.

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.
