Omega's BT40 Shrink Fit Chuck (G2.5) is a high-speed toolholding solution designed for BT40 spindles. It clamps 5 mm tool shanks using a heat-expanded shrink-fit, delivering exceptional concentricity and minimal runout at speeds up to 25,000 RPM. The 120 mm long body provides balanced rigidity for demanding milling and drilling tasks, helping you achieve consistent, precise results.

• G2.5 precision for minimal runout: Ensures tool concentricity and consistent accuracy across high-speed operations, resulting in tighter tolerances and smoother finishes.
• Shrink-fit grip for stability and vibration damping: Heat-expanded clamping creates a secure, wobble-free hold that reduces tool deflection and chatter for cleaner cuts and longer tool life.
• High-speed performance with a sturdy 120 mm body: Ready for demanding applications up to 25,000 RPM while maintaining balanced rigidity; compatible with 5 mm shanks for versatile tooling setups.

This chuck helps you streamline production with reliable, repeatable results at high speeds. The combination of precise concentricity, robust shrink-fit retention, and a long, stable body translates to better surface finishes, tighter tolerances, and fewer interruptions due to tool runout—empowering you to complete jobs faster with greater confidence.
