Description
The Omega BT50 ER Collet Chuck is a precision tool holder designed for BT50 spindle systems. It securely clamps ER32 collets to hold cutting tools with steady accuracy during machining operations. Ideal for job shops, engineers, tradespeople, and hobbyists, it delivers reliable tool retention and repeatable results for a range of milling tasks. With a 200 mm gauge length and Form AD/B construction, this chuck provides stable seating and consistent performance.
Operating in a speed range of 15,000 to 25,000 RPM, it supports both fine finishing and aggressive material removal while maintaining tight concentricity. The combination of G2.5 and G6.3 precision ratings indicates excellent tool alignment and minimal runout, which translates to smoother cuts and better surface finishes.
- ER32 compatibility for versatile tooling: Accepts standard ER32 collets, enabling a wide selection of cutting tools and quick, repeatable tool changes so you can tackle multiple jobs without changing holders.
- High-precision clamping with minimal runout: Engineered for top-tier concentricity (G2.5/G6.3), reducing vibration and delivering consistent accuracy at high speeds for better part quality.
- Robust BT50 form with stable 200 mm gauge length: Form AD/B design and precise gauge length ensure secure seating, durable engagement, and long-term reliability in demanding machining environments.
The BT50 ER Collet Chuck provides dependable retention, helps streamline setups, and supports a wide range of tooling and materials. By maintaining consistent tolerances and offering fast tool changes, it helps improve workflow, reduce downtime, and deliver reliable, repeatable results across finishing, profiling, and through-bore operations.
