Grade & Chip Control Technology
VP15TF Miracle Grade: This is a PVD-coated micro-grain carbide grade. The (Al,Ti)N coating provides high oxidation resistance and hardness, significantly reducing crater wear and flank wear. It is particularly effective for stable cutting of 304/316 stainless steel.
Universal Chipbreaker: Optimized for light to medium cutting. It prevents "bird-nesting" by providing reliable chip breaking at varying depths of cut, ensuring a clean high-surface finish.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel | 80 - 180 m/min | 0.05 - 0.20 mm/rev | 0.2 - 2.0 mm |
| Mild Steel | 100 - 250 m/min | 0.08 - 0.25 mm/rev | 0.5 - 2.5 mm |

VP15TF is your "go-to" universal grade for diverse materials. However, if your focus is strictly on mass production of steel in stable conditions, UE6020 (CVD coated) may offer higher speed capabilities. For high-speed finishing of carbon steel where gloss is critical, consider 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.
