TPMH090208-MV VP15TF
Mitsubishi Materials | High-Durability Miracle Coated Carbide
Edge Strength for Demanding Boring Tasks
The Mitsubishi TPMH090208-MV VP15TF is a high-toughness PVD coated carbide insert. Featuring the legendary Miracle Coating (Al-Ti-N), this grade provides extreme heat resistance and prevents edge chipping. With an 0.8mm corner radius, this long-tail versatile insert offers significantly higher feed capabilities and edge durability than smaller radius variants, making it the ideal choice for CNC boring in Stainless Steels and Alloy Steels where tool pressure is a factor.

Miracle PVD Grade VP15TF
The VP15TF grade combines a micro-grain carbide substrate with an Al-Ti-N PVD coating. This provides a "tough-hard" surface that prevents Built-Up Edge (BUE). It is particularly effective for stainless steel turning where material adhesion is the primary cause of tool failure.
MV Multi-Value Chipbreaker
The MV chipbreaker is designed for stability. While finishing chipbreakers can be brittle, the MV design handles depth of cut variations gracefully. Combined with the 0.8mm radius, it allows for high-efficiency machining in rough-to-finish operations.

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.
