DCMT11T308-MV VP15TF
High-Security Edge | Miracle PVD Technology | MV Stable Geometry
Built for Stability in Tough Environments
VP15TF Grade (Miracle PVD Coating): The VP15TF is a world-class micro-grain carbide grade coated with Mitsubishi’s proprietary "Miracle" (Al-Ti-N) technology. It offers an incredible fusion of hardness and impact toughness. This grade is specifically engineered to survive the thermal shocks and high temperatures of Stainless Steel and Inconel machining while providing superior resistance to notch wear.
MV Chipbreaker (Stable Semi-Finishing): The MV chipbreaker is the "all-terrain" geometry. It is designed to maintain consistent chip control even when the depth of cut varies. In materials like 304 or 316 stainless, the MV breaker prevents long, stringy chips from wrapping around the tool post, ensuring safe, lights-out production.
0.8mm Radius (The Heavy-Duty Edge): The "08" (1/32") radius offers the highest structural integrity for the DCMT series. This robust nose radius allows for aggressive feed rates and provides a thicker cutting edge that can withstand interrupted cuts or machining through raw forged surfaces without fracturing.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T308-MV | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | DCMT32.52-MV | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius is built for higher feed rates. Use high-pressure coolant for best chip evacuation in stainless steel.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 90 - 170 m/min | 0.12 - 0.30 mm/r | 0.50 - 2.50 mm |
| Alloy Steel (4140/4340) | 120 - 210 m/min | 0.15 - 0.35 mm/r | 0.80 - 3.00 mm |

VP15TF (PVD Miracle): The superior choice for stainless steel and unstable setups. The 0.8mm radius combined with VP15TF is much more resistant to "edge chipping" than CVD grades.
UE6110 (CVD Coated): Optimized only for high-speed continuous cutting of carbon steel. For anything tough, gummy, or unpredictable, stick with VP15TF.

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.
