The Omega BT40 Synchro Tapping Chuck with ER16 is designed for BT40 spindle machines and a wide range of tapping tasks. It covers a capacity range of M3 to M12, making it suitable for common small-thread applications in metalworking, maintenance, and fabrication environments. The built‑in synchro tapping mechanism keeps the chuck and spindle in lockstep, eliminating the need for rigid tapping cycles. Combined with high‑speed capabilities and robust construction, it delivers accurate threads, shorter cycle times, and longer tool life in everyday production. Synchronous tapping for precise threads: Keeps chuck and spindle in perfect sync to produce clean, consistent threads with fewer tapping defects. Wide tapping range (M3–M12) with ER16 collet: Offers versatile compatibility for common thread sizes and reliable, quick tool changes for efficient workflows. Rugged BT40 interface with high-speed capability: Designed for demanding production environments to deliver fast, accurate tapping with durable, long-lasting performance. This tapping chuck helps technicians, engineers, and shop operators streamline setups, improve thread quality, and reduce cycle times. With a stable BT40 interface and ER16 compatibility, it provides repeatable, dependable performance across jobs and supports longer tool life in busy production environments.
