The Omega BT40 Shrink Fit Chuck is a high-speed, tool-holding solution designed for BT40 CNC milling setups. It uses shrink-fit technology to heat-expand and securely grip the tool shank, delivering stable, consistent performance at speed for both professional shops and hobbyist workflows.

With a G2.5 precision rating, this chuck delivers excellent tool concentricity and minimal runout, helping you achieve accurate cuts and reliable results. Capable of up to 25,000 RPM, it handles demanding tasks with ease. The design accommodates an 8 mm shank and measures 120 mm long, making it a straightforward upgrade for compatible BT40 systems.

  • Secure shrink-fit grip for 8 mm shanks: Heat-expanded clamping creates a firm, uniform hold on the tool, delivering consistent retention and reducing runout during high-speed cutting.
  • G2.5 precision for concentricity: Tight tolerances ensure accurate tool positioning and repeatable results across your projects.
  • High-speed performance with vibration damping: Designed for up to 25,000 RPM, the shrink-fit approach stabilizes the tool, lowers deflection, and supports a smoother surface finish.

This BT40 shrink-fit chuck helps you optimize workflows by speeding up tool changes, improving cut quality, and delivering dependable performance in demanding applications. Built for durability and consistent results, it’s a reliable choice for engineers, machinists, and serious hobbyists alike.
