The Omega BT40 Shrink Fit Chuck is a precision tool-holding solution built for high-speed machining. It uses heat expansion to securely grip tool shanks, delivering stable engagement even under heavy cuts. With a compact 120mm length, it fits neatly into tight setups while maintaining rigidity.
With a G2.5 precision rating, the chuck offers excellent tool concentricity and minimal runout. It supports speeds up to 25,000 RPM, enabling demanding tasks with confidence. The shrink-fit design dampens vibration and reduces tool deflection, helping you achieve consistent finishes.
- G2.5 precision for minimal runout: Ensures tool concentricity and consistent results during high-precision cuts.
- Shrink-fit heat expansion for stability: Firmly grips the tool shank and provides vibration damping to reduce deflection and improve surface finish.
- High-speed performance up to 25,000 RPM: Handles demanding machining tasks with speed and accuracy, boosting productivity.
By combining precise concentricity with secure shrink-fit clamping and high-speed capability, the BT40 Shrink Fit Chuck helps you achieve repeatable part quality, minimize tool wear, and streamline setups. The result is reliable performance across a range of demanding applications, from finishing passes to roughing operations, with confidence in every cut.
