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
| Workpiece Material | Cutting Speed ($v_c$) | Feed Rate ($f$) |
|---|---|---|
| Stainless Steel (304/316) | 70 - 140 m/min | 0.03 - 0.12 mm/rev |
| Carbon / Alloy Steel | 90 - 170 m/min | 0.04 - 0.15 mm/rev |
MODULAR SYSTEM COMPATIBILITY
This insert requires a GY Series Holder Body combined with a specific Modular Blade.
