The Omega BT40 Shrink Fit Chuck is a precision tool holder designed for BT40-spindle CNC machines, engineered to securely grip 3 mm shank cutting tools at high speeds. It’s ideal f or engineers, machinists, and shops that demand tight tool concentricity and reliable performance in high-speed milling. With a G2.5 precision rating and a maximum speed of 25,000 RPM, this shrink-fit chuck delivers consistent runout control and robust vibration damping, helping you achieve accurate cuts, better surface finishes, and longer tool life. G2.5 precision and concentricity: Delivers exceptional tool concentricity with minimal runout, ensuring accurate, repeatable results across every pass. Shrink-fit clamping for 3 mm tool shanks: Heat-induced expansion securely grips the tool shank, providing stable holding, reduced vibration, and improved surface finishes. BT40 taper and high-speed reliability: Designed for BT40 spindles with a robust 160 mm body, optimized to perform reliably up to 25,000 RPM in demanding milling tasks. By combining precision concentricity, secure shrink-fit clamping, and high-speed capability, this chuck helps maintain tool accuracy, reduce part scrap, and enhance overall workflow—the result is consistent quality, faster cycle times, and increased confidence in every machining operation.
