GY2M0300F150N-BM VP20RT
Mitsubishi Materials | GY Series Full Radius Profiling System
The Mitsubishi GY2M0300F150N-BM VP20RT is a high-performance full radius grooving insert specifically engineered for profiling and copying operations. Part of the modular GY Series, this 3.0mm width insert utilizes the VP20RT Miracle PVD coating to deliver unmatched stability when machining Stainless Steel and high-temperature alloys. The BM chipbreaker is optimized for medium-range profiling, providing superior chip control in multi-directional cutting.

VP20RT Miracle Coating
The VP20RT grade is Mitsubishi's premium PVD grade designed to handle the high thermal loads of stainless steel grooving. It features high adhesion strength and resistance to thermal cracking, making it the industry standard for tough-to-machine materials where precision and tool life are critical.
BM Chipbreaker Strategy
The BM (Full Radius) chipbreaker is specialized for profiling and copying. Unlike flat-bottom breakers, the BM geometry is shaped to break chips effectively during side-turning and curved paths, preventing surface marring from long chip bird-nesting.
Recommended Cutting Parameters

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.
