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.
