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
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.
