(Note 1) Cutting conditions ae/Dc=70%. (Note 2) It’s possible to occur vibrations in certain cases. Please reduce depth of cut and / or reduce cutting conditions in following cases: - When using long shank; - When using long tool overhang with arbor type; - When application has poor clamping rigidity or when using a low rigidity machine. (Note 3) PH5… and PHS… can be used wet or dry. PH7… use only air.

1 Unalloyed Steel 125-220 ✓ ✓ ✓ ✓ ✓
- The width of the parallel land (F) of the insert is 2,0mm.
| P | 2 | Low-Alloyed Steel | 220-280 | ✓ | ✓ | ✓ | ✓ | ✓ | |
| 3 | High-Alloyed Steel | 280-380 | - Width a cutter of 10 inserts and using a feed per tooth (fz) of 0,3mm, i.e. 33% bigger than the parallel land. | ||||||
| ✓ | ✓ | ✓ | ✓ | ✓ | |||||
| 4 | SS - Ferritic / Martensitic | 200-330 | ✓ | - To obtain a good surface finish, the feed per revolution should be a maximum of 80% of 2mm = 1,6mm. | |||||
| M | 5 | SS - Austenitic | 200-330 | ✓ | - Then wiper insert will have a parallel land (Fw) with a width of approximately 7,6mm. | ||||
| 6 | SS - Austenitic-ferritic (Duplex) | 230-260 | ✓ | ||||||
| 7 | Malleable Cast Iron | 130-230 | - Result: Feed per revolution (fn) could be increased from 1,6mm to 60% of 7,6mm = 4,56mm. |
