DCMT070202-SV VP15TF
Miracle PVD Technology | SV Precision Chipbreaker | 0.2mm Radius
Optimized for Intricate Precision Turning
VP15TF Grade (The Miracle PVD): The VP15TF grade features Mitsubishi's proprietary Al-Ti-N PVD coating. This "Miracle" technology provides a thin, high-adhesion layer that maintains an ultra-sharp cutting edge. It is designed to resist oxidation and built-up edge (BUE) when machining sticky materials like 300-series Stainless Steels or mild steels.
SV Chipbreaker (Profiling Specialist): The SV geometry is specifically designed for small-depth finishing and profiling. It provides excellent chip control at low feed rates, preventing long stringy chips that can damage the surface finish of delicate components or wrap around the workpiece.
0.2mm Radius (Ultra-Low Force): The "02" (1/128") radius reduces radial cutting forces to an absolute minimum. This is critical for preventing vibration and chatter in slender workpieces, small-diameter boring, or when working with flexible materials.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT070202-SV | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCMT21.50.5-SV | 1/4" | 3/32" | 0.0078" (1/128") |
Recommended Cutting Parameters
*The 0.2mm radius is designed for finishing. Avoid high feeds to prevent edge breakage.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 90 - 180 m/min | 0.03 - 0.10 mm/r | 0.10 - 0.80 mm |
| Alloy Steel (4140) | 110 - 240 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.00 mm |
Pro-Tip: SV vs. FV Chipbreaker
SV Chipbreaker: Best for wide-range profiling where chip control is difficult across varying diameters.
VP15TF Grade: Unlike CVD grades, the PVD coating preserves the 0.2mm edge radius's sharpness, which is vital for preventing the tool from "rubbing" the workpiece.

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.
