TPGH080204L-FS VP15TF
Mitsubishi Materials | PVD Coated "Miracles" Grade (Left-Hand)
The Mitsubishi TPGH080204L-FS VP15TF is a high-performance Left-Hand (L) PVD coated carbide insert designed for precision finishing. Utilizing the legendary VP15TF Miracles grade, this insert provides exceptional stability and tool life when CNC machining stainless steel, carbon steel, and cast iron. The FS chipbreaker is engineered for super-finishing at light depths of cut, making it a critical long-tail precision tool for high-tolerance boring operations.

VP15TF Miracles Coating
The VP15TF grade is a micro-grain carbide substrate with an AlTiN-based PVD coating. This "Miracles" series is legendary for its stable machining capabilities. It resists welding and thermal cracking, making it the ideal choice for lathe turning operations in sticky materials like 300-series stainless steel.
FS "Super-Finish" Breaker
The FS chipbreaker is a G-class finishing geometry. It features an ultra-sharp cutting edge and high-positive rake angle to reduce cutting forces. It provides excellent chip evacuation even at the lightest depths of cut, preventing surface marring on critical bores.

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.
