Maximum Edge Security | Miracle PVD Coating | MV Versatile Geometry
Engineered for Stability in Difficult Materials
VP15TF Grade (Miracle PVD Technology): The VP15TF is widely regarded as the most versatile grade in the Mitsubishi lineup. It utilizes a high-toughness micro-grain carbide substrate paired with a Miracle PVD coating. This combination provides extreme resistance to "Built-Up Edge" (BUE) and thermal cracking, making it the top choice for Stainless Steels (304/316) and Alloy Steels.
MV Chipbreaker (Medium-V Control): The MV geometry is a master of chip management. It is designed to handle varying depths of cut while maintaining a stable cutting edge. Whether you are performing semi-finishing or light roughing, the MV breaker ensures chips are broken effectively to prevent damage to the workpiece surface.
0.8mm Radius (High Feed Strength): The "08" (1/32") radius is the strongest option for the 07-size insert. It provides a massive boost in edge durability compared to the 0.4mm version, allowing for higher feed rates and better performance in interrupted cuts or when machining through rough outer scales of raw stock.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT070208-MV | 6.35 mm | 2.38 mm | 0.80 mm |
| Imperial | DCMT21.52-MV | 1/4" | 3/32" | 0.0315" (1/32") |
Recommended Machining Parameters
*The 0.8mm radius allows for higher feeds. Ensure your machine setup is rigid to prevent vibration.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 160 m/min | 0.10 - 0.25 mm/r | 0.40 - 1.50 mm |
| Carbon/Alloy Steel | 120 - 200 m/min | 0.12 - 0.30 mm/r | 0.50 - 2.00 mm |
Compatible Tool Holders
Works perfectly with standard 07-series SDJCR/L or SDUCR/L holders:
Shop 07 Series HoldersPro-Tip: VP15TF vs. UE6110
VP15TF (PVD Coating): Excellent for "gummy" materials like stainless steel and low-carbon steel. Use this when you have light interruptions or unstable setups.
UE6110 (CVD Coating): Use UE6110 for high-speed continuous turning in pure steel only. VP15TF is far superior for stainless steel and general multi-material workshops.
