ID Whirling

Driven by the passion for highest productivity, Schwanog sets new productivity standards in regard to internal whirling.

ID whirling tools are used mainly in the orthopedic and dental industries to efficiently manufacture internal threads, particularly in bone screws and bone plates. Standard sizes M1 to M5 and ANSI are available from stock, specials (ACME, Buttress) upon request. The ID whirling process is similar to the OD whirling process as the main spindle is running at low rpm's while the tool is running at high rpm's.

Orthopedic or dental high tech applications call often for a maximum in precision and longevity. Schwanog ID whirling tools (thread mills) precisely and efficiently produce internal threads on bone screws and bone (cervical) plates. Schwanog ID whirling tools for internal threads are available in thread sizes from M1 to M5, with 1 or 3 flutes. ANSI sizes and specials available upon request.
