GPMT090304-U2 VP15TF
Mitsubishi Materials | The Miracle Coated All-Rounder
The Mitsubishi GPMT090304-U2 VP15TF is a precision parallelogram turning insert engineered for high-performance machining. Featuring the legendary VP15TF Miracle Coating (PVD), this insert provides exceptional versatility across Stainless Steel (M), Carbon Steel (P), and Super Alloys (S). The U2 chipbreaker is specialized for medium-range copying and turning, offering a perfect balance between edge strength and smooth chip evacuation.
Technical Data Sheet

|---|---|
| ANSI Specification (Inch) | GPMT 32.51-U2 |
| Material Grade | VP15TF (PVD Miracle Coating) |
| Corner Radius | 0.4 mm (1/64") |
| Insert Thickness | 3.18 mm (1/8") |
VP15TF Miracle Grade
The VP15TF grade utilizes Mitsubishi's high-adhesion PVD coating technology. It is highly resistant to crater wear and built-up edge (BUE), making it the industry benchmark for machining sticky materials like SUS304/316 stainless steel and heat-resistant alloys.
U2 Chipbreaker Logic
The U2 Chipbreaker is specifically designed for medium copying and light-to-medium turning. Its geometry facilitates stable chip breaking even at varying depths of cut, providing high-quality surface finishes in complex profiling 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.
