The Omega BT40 Shrink Fit Chuck is a high-precision tool holder designed for BT40 spindle systems and high-speed milling. Its shrink-fit design uses heat to securely grip tool shanks, delivering solid stability and reduced runout for cleaner, more accurate cuts.

With a G2.5 precision rating, a 10 mm shank fit, and a long 160 mm body, it keeps tools running true up to 25,000 RPM. This makes it a reliable choice for engineers, machinists, and hobbyists who demand repeatable results and smooth finishes even on demanding materials.

• G2.5 Precision Concentricity: Delivers tight runout for accurate, repeatable cuts every time.
• Secure Shrink-Fit Grip: Heat-expansion clamping locks in 10 mm tool shanks for stable performance and reduced deflection and vibration, improving surface finish.
• High-Speed Durability up to 25,000 RPM: Built to handle demanding milling tasks with consistent performance and long life in busy shops.

Designed to streamline your workflow, the BT40 shrink-fit chuck minimizes tool movement and chatter, enabling faster passes with predictable results. The combination of precise concentricity, secure grip, and high-speed capability translates into lower scrap, less rework, and better finishes across a range of materials. Built with durable materials and a robust construction, it stands up to regular use in busy production environments, giving you confidence in every cut and ease of integration with existing tooling setups.
