DCGT11T302L-F VP15TF
G-Class Ground Precision | VP15TF Miracle PVD | F-Fine Cut Geometry
Engineered for Micron-Level Accuracy
VP15TF Grade (Miracle PVD Shield): The VP15TF is Mitsubishi's benchmark PVD grade. The Miracle (Al-Ti-N) coating provides extreme hardness and heat resistance. Because it is applied via Physical Vapor Deposition, the coating remains thin enough to preserve the periphery-ground sharpness of the DCGT series, making it ideal for Carbon Steel, Alloy Steel, and Stainless Steel.
F-Chipbreaker (Micro-Finishing): The F-geometry is a high-rake, positive chipbreaker designed for finishing depths. It excel at controlled chip evacuation even at extremely light depths of cut ($Ap < 0.5mm$), preventing the "birds-nesting" that ruins surface finishes on CNC lathes.
G-Class Precision Ground: Unlike standard DCMT inserts, the DCGT is ground on all sides. This results in a razor-sharp edge and an indexing tolerance of $\pm 0.025mm$ or better. This is the "Left-Hand" (L) version for specific tool paths and back-turning.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCGT11T302L-F | 9.525 mm | 3.97 mm | 0.20 mm |
| Imperial | DCGT32.50.5L-F | 3/8" | 5/32" | 0.0078" |
Recommended Cutting Parameters
*The 0.2mm radius requires high spindle speeds and light feeds to prevent edge chipping.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 120 - 240 m/min | 0.03 - 0.10 mm/r | 0.05 - 0.80 mm |
| Stainless (SUS304/316) | 90 - 170 m/min | 0.03 - 0.08 mm/r | 0.05 - 0.60 mm |

Shop Left-Hand 11 HoldersGrade Comparison: VP15TF vs. NX2525
VP15TF (PVD Carbide): Your all-rounder. Choose this for toughness, stainless steel, and when the machine speed is limited. It handles interrupted cuts better.
NX2525 (Cermet): Choose for high-speed continuous finishing in steel. It provides a better "mirror" finish but is more brittle than VP15TF.

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.
