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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
