Miracle PVD Technology | Universal Material Mastery | MV Precision Geometry
The Ultimate Multi-Material Solution
VP15TF Grade (Miracle PVD Coating): The VP15TF is Mitsubishi’s most successful general-purpose grade. It features a micro-grain carbide substrate coated with "Miracle" (Al-Ti-N) technology. This coating offers extreme heat resistance and high lubricity, which prevents Built-Up Edge (BUE)—the leading cause of tool failure in stainless steel and low-carbon steel.
MV Chipbreaker (Medium-V Finishing): The MV geometry is engineered for semi-finishing to finishing. Its sharp rake angle allows the tool to slice through ductile materials easily, while the chip-breaking pocket ensures that chips are broken into small, manageable curls, preventing "bird-nesting" on your workpiece.
0.4mm Radius (Universal Balance): The "04" (1/64") radius is the industry standard for a reason. It provides a robust cutting edge for light roughing while remaining sharp enough to produce excellent surface finishes on precision components.

VP15TF (PVD Miracle): The first choice for stainless steel, heat-resistant alloys, and small parts. It provides extreme edge toughness for interrupted cuts.
UE6110 (CVD Coated): Use UE6110 only for high-speed continuous turning of steel in stable conditions. For general multi-material work, VP15TF is more reliable and versatile.

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.
