The Omega BT40 Shrink Fit Chuck is a precision tool holder designed for BT40 spindle systems and high-speed milling. It uses heat-expanded shrink-fit clamping to securely grip 3 mm tool shanks, delivering consistent concentricity and stable cutting at speeds up to 25,000 RPM.

With a G2.5 precision rating, this chuck minimizes runout for predictable toolpaths, helping you achieve better surface finish and tighter tolerances. The shrink-fit design dampens vibration, reducing deflection and chatter to keep your tools productive and your parts precise.

• Ultra-precise concentricity with minimal runout: G2.5 rating ensures tool alignment stays true, improving accuracy and surface finish across every pass.
• Secure shrink-fit grip with vibration damping: Heat expansion clamps the 3 mm shank firmly, reducing deflection and chatter for consistent cuts and longer tool life.
• High-speed performance for demanding work: Rated to 25,000 RPM with a 90 mm long body, providing balanced, stable operation even at top speeds.

This chuck helps you streamline your machining workflow by delivering repeatable, high-quality results with less rework. The combination of precise concentricity, secure clamping, and high-speed stability translates into faster cycle times, cleaner finishes, and longer tool life—whether you're producing precision components, fixtures, or prototyping parts. Confidently choose this BT40 Shrink Fit Chuck to maximize uptime and deliver reliable performance across your most demanding milling tasks.
