Case study
Disk brake
| Material | FC250 |
| Cutting speed | 640 m/min |
| Feed | 0.3 mm/rev |
| DOC | 0.5 mm |
| Coolant | DRY |
| AC11 | 130 pcs / corner |
| Competitor’s Ceramic | 60 pcs / corner |
AC11 doubled the tool life of the competitor’s black ceramic.
Cylinder liner
| Material | Chilled iron |
| Cutting speed | 610 m/min |
| Feed | 0.3 mm/rev |
| DOC | 3 mm |
| Coolant | DRY |
| AW21 | 70 pcs / corner |
| Competitor’s ceramic | 30 pcs / corner |
AW21 doubled the tool life and achieved superior surface finishes on the part compared to the competitor’s insert.
