TPGH110304L-FS VP15TF
Mitsubishi Materials | PVD Coated "Miracles" Grade (Left-Hand)
Precision Finishing Overview
The Mitsubishi TPGH110304L-FS VP15TF is a premium Left-Hand (L) PVD coated carbide insert engineered for stable finishing. Utilizing the legendary VP15TF Miracles grade, it offers a tough micro-grain substrate that excels in heat resistance. The FS chipbreaker is specialized for super-finishing at light depths of cut, making it a critical long-tail precision tool for CNC machining of stainless steel, carbon steel, and alloyed materials where edge integrity is vital.

VP15TF Miracles Coating
The VP15TF grade features a micro-grain carbide substrate with an AlTiN-based Miracle coating. This grade is optimized for stable machining by reducing chemical wear and thermal cracking. It is highly effective for lathe turning in stainless steel where built-up edge (BUE) often ruins surface quality.
FS "Super-Finish" Breaker
The FS chipbreaker provides a high-positive rake angle that significantly lowers cutting resistance. This allows for superior chip evacuation even at light depths of cut, ensuring that your CNC boring process results in a flawless, scratch-free surface finish.

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.
