The Omega BT40 Shrink Fit Chuck is a precision tool-holding solution designed for BT40 spindle systems used in high-speed milling and drilling. It uses a heat-expanded shrink-fit design to securely grip a 14 mm tool shank, delivering rigid, vibration-damped performance at high speeds.

With a G2.5 precision rating, this chuck delivers excellent tool concentricity and minimal runout, helping you achieve accurate hole locations, smoother surface finishes, and repeatable results. Built for demanding environments, it operates up to 25,000 RPM, making it well-suited for fast, productive machining while maintaining tight tolerances.

• G2.5 Precision Concentricity: Ensures minimal runout for accurate features and consistently smooth finishes, even at high RPMs.
• Secure Shrink-Fit Clamping: Heat-activated expansion grips the 14 mm tool shank firmly, delivering superior stability and reduced vibration during heavy cuts.
• High-Speed Capability with BT40 Fit: Optimized for up to 25,000 RPM, with a practical 160 mm overall length for reach and rigidity in demanding applications.

This chuck supports faster, more predictable machining outcomes by providing a repeatable, sturdy interface between your BT40 spindle and cutting tools. Its combination of precise concentricity, robust shrink-fit grip, and high-speed capability helps improve workflow efficiency, reduce deflection, and enhance surface finish across a wide range of milling and drilling tasks.
