Material & Chip Control Technology
VP15TF Miracle Grade (PVD Coating): This grade consists of a micro-grain carbide substrate coated with a specialized Al-Ti-N (Miracle Coating). It provides exceptional oxidation resistance and hardness, effectively preventing built-up edge (BUE) and ensuring stable performance in interrupted cutting.
MV Chipbreaker: The MV geometry is designed for medium-range applications. It provides excellent chip control across a wide range of feed rates, reducing cutting resistance and ensuring a high surface finish on your workpiece.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |
| Carbon/Alloy Steel | 100 - 250 m/min | 0.15 - 0.35 mm/rev | 1.0 - 3.0 mm |

VP15TF is your most versatile choice for general machining. However, if you are focusing strictly on mass production of steel under stable conditions, consider UE6020 for higher speed. If your task is purely high-speed finishing of carbon steel, NX2525 cermet may provide a superior mirror finish.
