VP15TF Grade & Geometry Analysis
VP15TF Miraculo Coating: This PVD coated carbide features a micro-grained substrate that balances hardness and toughness. The coating reduces built-up edge (BUE), which is common when machining 304/316 stainless steel. The PVD process allows for a sharper cutting edge than CVD, significantly reducing cutting forces.
Stable Profiling: The 35° diamond shape offers superior accessibility for complex precision profiling. The chipbreaker design ensures effective chip control even at varying depths of cut, protecting the workpiece surface from scratches.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (M) | 80 - 180 m/min | 0.15 - 0.35 mm/rev | 0.8 - 3.0 mm |
| Carbon/Alloy Steel (P) | 100 - 220 m/min | 0.15 - 0.40 mm/rev | 1.0 - 3.5 mm |

VP15TF is the "Universal Solution" for mixed-material jobs. For high-speed mass production of only carbon steel, the UE6110 (CVD) is faster. For difficult-to-cut superalloys (Inconel/Titanium), consider the MP9015 grade. For mirror-finish finishing on steel, use the NX2525 cermet grade.

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.
