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.

Recommended Cutting Parameters
*VP15TF handles varying conditions well. For optimal tool life, ensure consistent coolant application.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 180 m/min | 0.05 - 0.20 mm/r | 0.30 - 2.00 mm |
| Carbon/Alloy Steel | 120 - 220 m/min | 0.08 - 0.22 mm/r | 0.50 - 2.50 mm |

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.
