Grade & Chipbreaker Analysis
US735 Grade (CVD Coated): Specifically developed for stainless steel turning. It features a high-toughness carbide substrate that excels in interrupted cutting. The coating effectively resists built-up edge (BUE) and heat deformation.
MV Chipbreaker: The "Medium Volumetric" geometry provides an excellent balance between chip control and cutting edge strength, making it ideal for rough-to-finish turning on CNC machines.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (304/316) | 80 - 180 m/min | 0.10 - 0.35 mm/rev |
| Hardened Alloys | 40 - 90 m/min | 0.08 - 0.25 mm/rev |
