DCGT11T302R-F VP15TF
G-Class Ground Precision | VP15TF Miracle PVD | F-Fine Cut Geometry
The Precision-Ground Advantage
VP15TF Grade (Miracle PVD Shield): The VP15TF grade is Mitsubishi’s premier universal PVD coating. Utilizing a micro-grain carbide substrate and (Al,Ti)N Miracle Coating, it offers an exceptional balance of wear resistance and toughness. The PVD process ensures the coating is thin and uniform, preserving the razor-sharpness of the ground edge.
F-Chipbreaker (Finishing Specialist): The F-geometry is a high-positive rake chipbreaker designed specifically for finishing. It excels at breaking chips at extremely low depths of cut (under 0.5mm), preventing the "bird-nesting" that can scratch delicate surface finishes.
0.2mm Micro-Radius: The 02 radius is essential for high-precision profiles. It reduces radial cutting pressure, making it the perfect choice for internal boring in small diameters or turning long, thin parts where vibration (chatter) is a concern.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCGT11T302R-F | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCGT32.50.5R-F | 3/8" | 5/32" | 0.0078" |
Recommended Finishing Parameters
*The 0.2mm radius requires high spindle speeds (RPM) and light feed rates to prevent edge fracture.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Alloy Steel / SCM | 130 - 250 m/min | 0.03 - 0.10 mm/r | 0.05 - 0.80 mm |
| Stainless Steel (300/400) | 90 - 180 m/min | 0.03 - 0.08 mm/r | 0.05 - 0.60 mm |
Compatible High-Precision Holders
Maximum indexing accuracy when paired with SDJCR or SDUCR 11-series holders:
Shop SDJCR 11 HoldersPro-Tip: DCGT Ground vs. DCMT Molded
DCGT (Ground): The cutting edge is up to 5 times sharper than a molded insert. Use this when your surface finish requirement is Ra 0.8 or better. The indexing repeatability is +/- 0.02mm, ensuring dimensional consistency.
DCMT (Molded): Choose for general-purpose roughing or semi-finishing where cost-per-edge is the priority and tolerances are more relaxed.

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.
