Omega Products BT40 Synchro Tapping Chuck - ER40 - Capacity M6 - M33

Omega BT40 Synchro Tapping Chuck (ER40) is a precision tapping solution built for BT40 spindle machines. Designed for engineers, technicians, and shop floors, it delivers fast, accurate tapping with a compact, robust profile that fits into tight setups while standing up to daily use.

Its synchronous tapping mechanism keeps the chuck and spindle in lockstep, providing true synchronized rotation for every thread. This results in improved thread quality, tighter tolerances, and smoother hole finishes—without relying on rigid tapping cycles or complicated programming.

• Synchronous Tapping for Consistent Threads: The integrated synchro design ensures the chuck and spindle rotate in perfect harmony, delivering clean, repeatable threads and reducing the risk of tapping errors across production runs.
• High-Speed Performance with Robust Construction: Built for fast tapping in BT40 spindles, the chuck combines precision machining with durable materials to withstand demanding jobs and minimize downtime, extending tool life.
• Wide Capacity (M6–M33) with ER40 Interface: Supports a broad range of taps within the ER40 range, enabling versatile use across multiple applications without constant tool changes.

This tapping chuck helps you streamline workflows, shorten cycle times, and achieve reliable results from setup to part finish. With sturdy build quality and a broad capacity range, it’s a dependable choice for daily production, skilled machining, and DIY projects that demand professional-level threading accuracy.
