Description

Product Overview

Thread whirling uses a rotating ring with several whirling inserts to cut a thread on slender bar stock in one operation. Compared with conventional threading, the process can increase production speed by 3–5 times.

Utiltools Switzerland supplies standard insert sets for common threads as well as made-to-order profiles for orthopaedic bone screws and dental implant screws.
