The Omega BT40 Shrink Fit Chuck is a precision tool-holding solution designed for BT40 spindle systems, optimized for high-speed milling and drilling. It uses heat-expanded shrink-fit clamping to securely grip the tool shank, delivering stable performance at speeds up to 25,000 RPM.

With a G2.5 precision rating, this chuck delivers exceptional tool concentricity and minimal runout, helping you achieve repeatable, accurate cuts. It is designed for 25 mm shank tools and features a long 160 mm body, providing versatile setup options and reliable rigidity for demanding applications.

• Shrink-fit grip with heat-expanded clamping: The controlled heat expansion creates a firm, vibration-damping connection to the tool shank, reducing deflection and promoting a consistently smooth finish.
• G2.5 precision for concentricity: Outstanding concentricity and minimal runout ensure precise tool paths and repeatable results across a range of milling and finishing tasks.
• Extended 160 mm reach for versatile setups: The long, rigid body enables flexible tool arrangements and stable cutting at up to 25,000 RPM, suitable for a variety of workholding needs.

In practice, this BT40 Shrink Fit Chuck helps you deliver reliable, high-quality results with tighter tolerances and better surface finishes. The combination of a secure heat-clamped grip, precise concentricity, and a robust long-format body supports faster changeovers, consistent performance, and improved overall workflow in busy machining environments.
