DCGT11T304R-F VP15TF
G-Class Ground Precision | VP15TF Miracle PVD | F-Finishing Geometry
Superior Precision Ground Engineering
VP15TF Grade (Miracle PVD Performance): The VP15TF is Mitsubishi’s premier universal PVD grade. Using a micro-grain carbide substrate and (Al,Ti)N Miracle Coating, it provides a hard, heat-resistant surface that prevents built-up edge (BUE). The PVD process ensures the coating remains thin and uniform, preserving the razor-sharpness of the ground edge—essential for finishing Stainless Steel and Alloy Steels.
F-Chipbreaker (Fine-Cut Specialist): The F-geometry is a high-rake, positive chipbreaker designed specifically for finishing depths. It provides excellent chip control even at low depths of cut, preventing long, stringy chips from scratching the finished surface or tangling around the workpiece.
G-Class Accuracy: Unlike molded DCMT series, the DCGT is precision ground on its entire periphery. This results in an indexing tolerance of ±0.025mm, ensuring that when you flip the insert to a new edge, your machine's offset requires minimal adjustment.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCGT11T304R-F | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | DCGT32.51R-F | 3/8" | 5/32" | 0.0157" (1/64") |
Precision Machining Recommendations
*The F-breaker is optimized for light loads. For best surface Ra, maintain consistent feed rates within the range below.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Alloy Steel (SCM/4140) | 140 - 280 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.50 mm |
| Stainless Steel (304/316) | 90 - 190 m/min | 0.05 - 0.12 mm/r | 0.10 - 1.20 mm |

Shop SDJCR 11 HoldersPro-Tip: Ground DCGT vs. Molded DCMT
DCGT (Ground): Best for aerospace or medical parts where tolerances are tighter than +/- 0.01mm. The ground edge significantly reduces cutting resistance and vibration.
DCMT (Molded): Use for general-purpose roughing or semi-finishing where the accuracy of the insert index is less critical than cost-per-edge.

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.
