Description: |
| Cutterhead for the bolt threading machine of patent 409,208. This cutterhead patent contains the key innovation that made Landis bolt threading machine so successful. Rather than using the usual radially oriented cutters, Landis arranged the cutters (chasers) tangentially, which was claimed to produce a superior cutting action with less friction and less power consumed. |
