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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
