Mitsubishi Materials | Ultra-Precision Miracle Coated Fine-Finishing
Extreme Precision for Small-Radius Finishing
The Mitsubishi TPMH110302-MV VP15TF is a specialized PVD coated carbide insert engineered for high-precision fine finishing. Featuring a sharp 0.2mm corner radius, it minimizes cutting resistance, making it the ideal long-tail precision tool for thin-walled workpieces and tight internal profiles. Utilizing the VP15TF Miracle Coating, this insert provides superior adhesion resistance for CNC boring in Stainless Steels, Alloy Steels, and Mild Steels.

The Miracle PVD Advantage
VP15TF is an AlTiN PVD coating over a micro-grain carbide substrate. This combination allows for a high cutting temperature while protecting the edge from wear. For stainless steel turning, it prevents the material from "welding" to the tip, which is the leading cause of poor surface finish in finishing operations.
MV Multi-Value Chipbreaker
The MV chipbreaker is specialized for stable chip control. In fine finishing, chips are often thin and "stringy." The MV geometry forces these chips to curl and break at low feed rates, protecting the workpiece surface from scratches in high-precision CNC tasks.

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.
