Mitsubishi Materials | Double-Sided 8-Corner Roughing Specialist
The Mitsubishi SNMU140812ANER-R VP15TF is a high-performance double-sided square milling insert engineered to maximize productivity while minimizing cost-per-edge. Featuring 8 usable cutting corners, this insert is designed for high-feed and heavy-duty face milling. The R-Breaker (Roughing) geometry is specifically built to withstand high impact, making it the definitive choice for interrupted cuts and heavy scale removal in steel and stainless steel alloys.

VP15TF Miracle PVD Coating
The VP15TF grade is Mitsubishi's premier universal Miracle PVD coating. It is designed to maximize tool life in a broad spectrum of materials, specifically milling carbon steel and stainless steel. The nano-layered coating provides excellent oxidation resistance and prevents chip welding, even at high cutting temperatures.
R-Breaker (Heavy Roughing)
The R-Breaker features a reinforced cutting edge designed for heavy roughing milling. Unlike finishing breakers, the "R" geometry prioritizes fracture resistance. This makes it the ideal long-tail solution for machining workpieces with uneven surfaces, casting skins, or when the process involves heavy interrupted cutting.

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.
