GY2M0200D020N-MS VP20RT
Mitsubishi Materials | GY Series Precision Grooving System
The Mitsubishi GY2M0200D020N-MS VP20RT is a specialized 2.0mm width insert engineered for the high-rigidity GY Series modular grooving system. This specific model features the MS chipbreaker (Medium-Low Feed), making it the superior choice for precision finishing and controlled chip breaking in Stainless Steel and Heat-Resistant Alloys. Coated with the legendary VP20RT Miracle PVD, it ensures maximum tool life in the most demanding thermal conditions.

| Material Grade | VP20RT (Miracle PVD Coating) |
VP20RT Miracle PVD
The VP20RT grade is a "Miracle" PVD coated carbide that provides an exceptional balance of wear resistance and toughness. It is designed to resist thermal cracking and notch wear, common issues when grooving difficult-to-cut materials like SUS304 or Inconel.
MS Chipbreaker Advantage
The MS (Medium-Low Feed) chipbreaker is optimized for precision finishing. Unlike the MM breaker, the MS geometry focuses on low feed chip control, preventing the "long chip" issues often seen during shallow grooving or fine turning cycles.
Optimization: Cutting Parameters

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.
