GY2M0300F030N-GM VP20RT
Mitsubishi Materials | GY Series Versatile Grooving System
The Mitsubishi GY2M0300F030N-GM VP20RT is a professional-grade 3.0mm grooving insert part of the modular GY Series. Engineered with the legendary VP20RT Miracle PVD coating, this insert provides a superior balance of toughness and wear resistance. It is the primary choice for machining Stainless Steel, Heat-Resistant Alloys, and Carbon Steels in demanding CNC lathe environments.
Technical Data Sheet
| ISO Code (Metric) | GY2M0300F030N-GM |
|---|---|
| ANSI Code (Inch) | GY2M 118-F012-GM |
| Groove Width (CW) | 3.0 mm (.1181") |
| Corner Radius (RE) | 0.3 mm (.0118") |
| Coating Grade | VP20RT (Miracle PVD) |
VP20RT Grade Advantage
The VP20RT Miracle PVD grade is optimized for high-toughness requirements. It excels in preventing thermal cracking and resisting built-up edge (BUE) during the machining of sticky materials like SUS304/316 stainless steel. Its stable performance makes it ideal for interrupted cuts.
GM Chipbreaker Geometry
The GM (General Machining) chipbreaker is an "all-round" performer. It is designed to handle a wide range of feed rates and depths of cut. Its geometry ensures stable chip breaking, preventing long chips from scratching the workpiece surface or tangling in the CNC spindle.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (300/400) | 80 - 160 m/min | 0.05 - 0.18 mm/rev |
| Carbon & Alloy Steel | 100 - 190 m/min | 0.08 - 0.22 mm/rev |

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.
