The Omega BT40 Shrink Fit Chuck is a precision tool-holding solution designed for BT40 spindle systems. It securely grips 5 mm tool shanks with exceptional concentricity, helping you achieve accurate, repeatable machining results across a range of milling and drilling tasks.

Using a shrink-fit design, heat expansion clamps the tool shank firmly in place, delivering outstanding stability and vibration damping. With a G2.5 precision rating and a maximum speed of 25,000 RPM, this chuck is built to handle demanding high-speed applications while maintaining tight runout control and superior surface finish.

• G2.5 precision concentricity: Delivers excellent tool concentricity and minimal runout for accurate paths and consistent results across jobs.
• Secure heat-expanded shrink-fit grip: Clamps 5 mm shanks firmly to reduce vibration and deflection, improving finish quality and extending tool life.
• High-speed BT40 compatibility (up to 25,000 RPM): Engineered for fast, stable performance on BT40 spindles, maintaining precision even during demanding cuts.

Designed for professionals who require dependable performance in busy shops, this chuck helps streamline high-speed workflows. The combination of tight concentricity, secure tool grip, and high-speed capability translates to better surface finishes, reduced rework, and reliable results project after project—backed by a durable, purpose-built BT40 shrink-fit design.
