The Miracle Grade for Tough Alloys & Stainless
The Mitsubishi TPMN160308 VP15TF is a high-versatility PVD coated carbide insert engineered to conquer difficult-to-cut materials. Utilizing the proprietary Miracle Coating (VP15TF), this insert offers a perfect balance of micro-grain toughness and high-temperature hardness. With a robust 0.8mm corner radius and a 16mm triangular edge, it is the industry benchmark for CNC boring and turning in Stainless Steel, Carbon Steel, and Heat-Resistant Super Alloys.

Miracle PVD Coating Advantage
The VP15TF grade is a specialized PVD coated carbide featuring a micro-grain substrate and a high-aluminum content (Al,Ti)N coating. This combination provides excellent oxidation resistance and prevents chip welding. It is specifically designed to handle the work-hardening characteristics of 304 and 316 Stainless Steel, ensuring long tool life even in unstable cutting conditions.
TPMN Flat-Top Geometry
The TPMN geometry is a flat-top (no chipbreaker) design. This provides a very strong cutting edge that excels in heavy-duty boring and turning. By utilizing a sharp, positive 11° relief angle without a molded chipbreaker, the insert reduces cutting forces while maintaining the physical strength required for interrupted cuts and roughing passes.

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.
