DCGT070202L-F VP15TF
G-Class Ground Accuracy | VP15TF Miracle PVD | F-Fine Cut Geometry
The Micro-Finishing Standard
VP15TF Grade (Miracle PVD Performance): The VP15TF grade is Mitsubishi’s most versatile PVD coating. Using proprietary (Al,Ti)N Miracle technology, it creates a heat-resistant barrier that doesn't sacrifice edge sharpness. This is essential for the DCGT series, where a thick CVD coating would round off the precision-ground edge.
F-Chipbreaker (Precision Low-Force): The F-geometry is a specialized "Fine-cut" breaker. It features an extremely sharp rake angle designed to "peel" the material, reducing radial cutting forces to near zero. This is the ultimate solution for machining thin shafts or deep internal bores where chatter is a constant threat.
G-Class Fully Ground Tolerance: Unlike the DCMT (molded) series, the DCGT is precision ground on its entire periphery. This ensures that when you index the insert to a new edge, your machine's offset remains identical, making it perfect for high-tolerance automated production.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCGT070202L-F | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCGT21.50.5L-F | 1/4" | 3/32" | 0.0078" |
Fine-Cut Precision Parameters
*The 0.2mm radius is fragile. Ensure high spindle speeds and low feeds to prevent edge chipping.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 120 - 240 m/min | 0.03 - 0.08 mm/r | 0.05 - 0.80 mm |
| Stainless (SUS304/316) | 80 - 150 m/min | 0.02 - 0.06 mm/r | 0.05 - 0.60 mm |

Shop Left-Hand 07 HoldersPro-Tip: Ground DCGT vs. Molded DCMT
DCGT (Ground): The edge is 5x sharper than a molded insert. Use this for "Micro-Turning" where the part diameter is under 10mm or the surface finish requirement is Ra 0.4.
DCMT (Molded): Choose for general roughing where tolerance is relaxed and cost-efficiency is the goal.

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.
