Mitsubishi Materials | Large-Scale Precision Super-Finishing Specialist
Mastering Mirror Finishes in Heavy-Duty Boring
The Mitsubishi TPMH160302-FV VP15TF is a unique PVD coated carbide insert engineered for ultra-fine finishing. While the TPMH16 size is typically for heavy work, the 0.2mm corner radius and FV (Fine-Finish) chipbreaker allow for extreme precision on large-diameter components. Featuring the legendary VP15TF Miracle Coating, this long-tail super-finishing tool provides the thermal stability needed for CNC boring of Stainless Steels, Alloy Steels, and Heat Resistant Superalloys.

VP15TF Miracle PVD Grade
VP15TF is Mitsubishi’s proprietary multi-layer PVD coating. It is designed to withstand the high temperatures of super-finishing without losing edge sharpness. Unlike CVD coatings, which can be too thick for ultra-sharp radii, this PVD Miracle Coating adheres perfectly to the 0.2mm tip, preventing peeling and ensuring long tool life.
FV "Fine-Value" Geometry
The FV chipbreaker is an ultra-positive geometry designed to slice through material with minimal cutting resistance. This is critical for the 0.2mm radius version to prevent "rubbing" and work-hardening of the workpiece surface, especially in sensitive materials like 304/316 Stainless Steel.
Recommended Cutting Parameters

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.
