Omega BT40 Synchro Tapping Chuck is a precision tapping accessory designed for BT40 spindle machines. It works with ER20 tooling and supports taps from M3 to M16, delivering fast, reliable tapping with consistent thread quality. The integrated synchro mechanism keeps the chuck and spindle in perfect sync, eliminating the need for rigid tapping cycles and enabling smoother, more efficient production. Synchronous tapping for precise threads: The synchronized rotation between spindle and chuck produces clean threads with fewer rejects and shorter cycle times, improving overall part quality. BT40 interface with ER20 capacity: Compatible with BT40 spindles and ER20 tooling, delivering versatile tapping capability across a wide range of sizes and applications. Rugged, maintenance‑friendly construction: Built for demanding environments, with durable materials and robust clamping that resist wear and deliver reliable performance over time. This tapping chuck helps you streamline workflows by reducing setup and cycle times while delivering repeatable, high-quality threads. Its broad M3–M16 capacity and synchronized design mean you can tackle diverse tapping tasks with confidence, minimize downtime, and extend tool life for sustained productivity.
