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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
