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.

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.
