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.

| Corner Radius (RE) | 0.2 mm (.0079") |
| 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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
