QOMT1651R-M2 VP15TF
Mitsubishi Materials | AQX Heavy-Duty Multifunctional Milling Insert
The Mitsubishi QOMT1651R-M2 VP15TF is a high-capacity indexable milling insert designed for the large-scale AQX multifunctional cutter series. This "16" size insert is the ultimate choice for heavy-duty CNC milling, including deep pocketing, high-angle ramping, and large-shoulder milling. Engineered with the -M2 medium-cut chipbreaker and the proprietary VP15TF Miracle PVD coating, it provides extreme reliability for machining stainless steel, carbon steels, and heat-resistant alloys under high-load conditions.
Technical Specifications
| ISO/Metric Designation | QOMT1651R-M2 |
|---|---|
| ANSI Equivalent | QOMT 5451 R-M2 |
| Grade / Coating | VP15TF (Miracle Al-Ti-N PVD) |
| Thickness / Width | 5.1 mm / 16 mm Class |
| Chipbreaker Style | -M2 (Optimized for Medium Feed) |
VP15TF Miracle PVD Grade
The VP15TF grade utilizes a specialized micro-grain carbide substrate coated with Mitsubishi’s Miracle Al-Ti-N layer. This combination offers the toughness of carbide with the heat resistance of ceramics. It is designed to stop built-up edge (BUE) in its tracks, making it the perfect choice for milling gummy materials like 316 stainless steel or high-temp alloys.
-M2 Heavy-Duty Geometry
The -M2 chipbreaker is the workhorse of the AQX series. It features a reinforced cutting edge to handle the higher cutting resistance found in large-diameter milling. This geometry ensures smooth chip flow during high-feed milling, significantly reducing spindle vibration and improving the final thread surface finish.

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.
