DCMT070202-MV VP15TF
General Purpose Excellence | Miracle PVD Coating | Ultra-Precision 0.2mm Radius
High-Performance Versatility for CNC Lathes
VP15TF Grade (Miracle Coating): The VP15TF is Mitsubishi’s legendary PVD-coated carbide. Utilizing the "Miracle" coating technology, it offers an exceptional balance of wear resistance and toughness. This grade excels in Steel, Stainless Steel, and Cast Iron, making it the perfect choice for shops that need a single, reliable insert for diverse materials.
MV Chipbreaker (Medium-V Finishing): The MV geometry is designed for optimal chip control across a wide range of applications. Even at the light depths of cut required for micro-finishing, the MV breaker ensures chips are curled and broken, preventing surface entanglement and ensuring a high-quality finish.
0.2mm Radius (Anti-Chatter): The "02" (1/128") nose radius provides a very sharp cutting action. This minimizes radial cutting forces, making it the essential tool for machining slender parts, small internal bores, or components with very tight corner radius requirements.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT070202-MV | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCMT21.50.5-MV | 1/4" | 3/32" | 0.0078" (1/128") |
Recommended Cutting Parameters
*VP15TF is versatile; however, for the 0.2mm radius, keep feed rates low to maintain surface integrity.
| Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 120 - 220 m/min | 0.03 - 0.12 mm/r | 0.10 - 1.00 mm |
| Stainless Steel (304/316) | 80 - 180 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.80 mm |

Shop 07 Series HoldersPro-Tip: VP15TF vs. NX2525
VP15TF (PVD Carbide): The "All-Rounder." Use this for tough stainless steels and unstable setups. It is much more durable than cermet for interrupted cuts.
NX2525 (Cermet): Switch to NX2525 only when machining clean steel and requiring a mirror finish. VP15TF is significantly more secure for stainless steel and heat-resistant alloys.

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.
