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.

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.
