AOMT123608PEER-M VP20RT
Tough-Miracle PVD | Optimized for Interrupted Cuts & Stainless
The Mitsubishi AOMT123608PEER-M VP20RT is the rugged solution for the APX3000 milling system. While most inserts struggle with mechanical shock, the VP20RT grade is built for impact. Featuring a 0.8mm (0.0315") corner radius and a specialized substrate designed for fracture toughness, this insert excels in heavy-duty shoulder milling and applications involving interrupted cutting paths or work-hardening materials like 316 Stainless Steel.

Shop APX3000 Tool HoldersPro-Tip: When to choose VP20RT over VP15TF?
VP20RT (Tough Miracle): Use this grade if your inserts are chipping or breaking before they wear out. It is the gold standard for stainless steel and high-temp alloys.
VP15TF (General Miracle): Use for stable, continuous cutting in Carbon Steels where you want higher cutting speeds and a better surface finish.
