KYOCERA Launches TW Series Thread Whirling Tools for High Production Precision Machining

KYOCERA announces the launch of the TW Series Thread Whirling Tools, a new platform designed for high-efficiency thread production in precision small-part machining. Ideal for manufacturing critical components such as medical bone screws, the TW Series is engineered for Swiss-type lathes and supports a wide range of thread forms. Compatible with leading machine platforms including Citizen, Star, and Tsugami, the system delivers reliable and consistent thread generation for demanding industries such as medical and aerospace, where precision, surface finish, and process stability are essential. 

The TW Series features two insert configurations to meet varying production requirements. The L-Series, with a 9-flute cutter design and two-edge inserts, provides high-efficiency machining ideal for double start thread operations and cycle-time reduction. The T-Series offers a more economical option with a 6-flute design and three-edge inserts, delivering cost-effective performance for single start thread applications. Together, these options provide manufacturers with flexibility to balance productivity and tooling costs while maintaining consistent thread quality. 

Designed to support a broad range of thread geometries, including helix angles up to 30°, pitches up to 6mm, and multi-start threads, the TW Series provides precision thread production on components up to 10mm in diameter. Combined with durable coating technology and stable insert design, the platform ensures long tool life and dependable performance when machining difficult materials commonly used in medical implants, aerospace fasteners, and other high-precision threaded components. 

Custom inserts can be produced to support specialized thread geometries and application requirements.
