DCMT11T302-MV VP15TF
Precision Finishing Specialist | Miracle PVD Technology | 0.2mm Anti-Chatter Radius
Superior Control for Difficult-to-Cut Materials
VP15TF Grade (Miracle PVD Coating): The VP15TF is Mitsubishi’s world-renowned PVD-coated carbide. Engineered with the "Miracle" coating (Al-Ti-N), it provides a perfect balance of toughness and hardness. It is specifically effective at preventing Built-Up Edge (BUE) when machining gummy materials like 304/316 stainless steel and maintains sharp edges in heat-resistant super alloys.
MV Chipbreaker (Micro-V Precision): The MV geometry is a master of light-duty finishing. Its sharp rake angle slices through material with minimal cutting force, ensuring that heat is carried away by the chip rather than the workpiece. It is designed to provide excellent chip breaking even at extremely shallow depths of cut.
0.2mm Radius (Universal Precision): The sharp "02" (1/128") nose radius is critical for reducing radial cutting pressure. This makes it the ideal selection for machining long, slender shafts or components with thin walls where vibration (chatter) is a constant risk.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T302-MV | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCMT32.50.5-MV | 3/8" | 5/32" | 0.0078" |
Recommended Machining Parameters
*VP15TF thrives with consistent coolant flow. Adjust feeds carefully to protect the 0.2mm sharp tip.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.80 mm |
| Carbon/Alloy Steel | 120 - 220 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.00 mm |

VP15TF (PVD): Best for multi-material workshops. It is much tougher than cermet and survives light interruptions or vibration significantly better.
NX2525 (Cermet): Use NX2525 only when your setup is extremely rigid and you are machining carbon steel to a mirror finish. VP15TF is the "safer" and more versatile choice for most CNC operators.
