Iscar IC908 and IC907 are both PVD-coated grades for stainless and difficult materials, but have distinct strengths.
Grade Specifications
| Property | IC907 | IC908 |
|---|---|---|
| Substrate | Submicron carbide | Submicron carbide |
| Coating | SUMO TEC PVD AlTiN | PVD AlTiN multilayer |
| Hardness range | Steel + stainless to 35 HRC | Stainless + superalloys to 45 HRC |
| Best operation | General turning, roughing | Finishing, interrupted cuts |
304 Stainless Test (CNMG120408)
Vc=180 m/min, fn=0.30 mm/rev, ap=2 mm:
- IC907: 26 min — better tool life at higher feed
- IC908: 22 min — better surface finish
Inconel 718 Test
Vc=50 m/min, fn=0.20 mm/rev:
- IC907: 8 min — coating wears
- IC908: 14 min — better diffusion resistance
