Feed & Speeds For Annular Cutters
A guide to the selection of circumferential cutting speeds:
| feet/min | m/min | |
|---|---|---|
| Stainless Steel | 65 - 131 | 20-40 |
| Mild Steel | 98 - 164 | 30-50 |
| Cast Iron | 98 - 164 | 30-50 |
| Brass | 164 - 229 | 50-70 |
| Aluminum | 229 - 295 | 70-90 |
Test Drilling is very often the only way to determine the machinability of difficult materials. Use a small size cutter wherever possible in order to minimize trial costs.
