DCMT070202-FV VP15TF
Precision "FV" Chipbreaker | Miracle PVD Coating | 0.2mm Super-Radius
Mastering Micro-Finishing & Precision Profiling
VP15TF Grade (Universal Miracle PVD): The VP15TF utilizes Mitsubishi’s proprietary Al-Ti-N Miracle coating. This PVD layer is applied to a tough micro-grain carbide substrate, providing an extremely sharp edge that resists Built-Up Edge (BUE). It is universally capable across Stainless Steel (M-class), Steel (P-class), and Superalloys (S-class).
FV Chipbreaker (Finishing Specialist): The FV geometry is a "V-shaped" chipbreaker designed for shallow depths of cut. It ensures stable chip evacuation even at extremely low feed rates, preventing long "bird-nest" chips from marring the surface of your precision components.
0.2mm Nose Radius: The "02" radius is designed for ultra-precision. It allows for sharp internal corners and generates significantly less radial pressure than 0.4mm or 0.8mm radii, making it ideal for thin-walled parts or slender shafts where chatter is a major concern.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT070202-FV | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCMT21.50.5-FV | 1/4" | 3/32" | 0.0078" (1/128") |
Recommended Machining Parameters
*The 0.2mm radius is sensitive to high feeds. Stay within parameters for maximum surface quality.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 100 - 200 m/min | 0.03 - 0.12 mm/r | 0.10 - 0.80 mm |
| Alloy Steel (4140) | 120 - 250 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.00 mm |

Shop 07 Series HoldersPro-Tip: FV vs. Standard Geometry
FV Chipbreaker: Engineered for "Micro-Finishing." Use this when your depth of cut is less than 0.5mm to ensure chips don't wrap around the workpiece.
VP15TF Grade: Unlike CVD grades, the PVD coating on the 0.2mm edge is ultra-thin, preserving the absolute sharpness needed for mirror finishes.

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.
