The Omega BT40 Shrink Fit Chuck is a high-precision tool-holding solution designed for BT40 spindles. It securely grips 14 mm tool shanks and, with an overall length of 120 mm, delivers stable, accurate performance in high-speed milling environments. Rated for up to 25,000 RPM, this chuck helps you achieve consistent runout control and superior surface finish across demanding jobs.

Engineered with a G2.5 precision rating, it delivers excellent concentricity and minimal runout, keeping tools on-center for repeatable results. The shrink-fit design uses controlled heat expansion to firmly grip the tool shank, offering both stability and effective vibration damping that minimizes deflection and chatter during fast, heavy-cutting operations.

• G2.5 precision for minimal runout: Delivers excellent concentricity and repeatable accuracy, so every pass produces predictable, high-quality cuts.
• 25,000 RPM high-speed capability: Supports demanding milling with stable grip at top speeds, enabling efficient material removal and smooth finishes.
• Secure shrink-fit grip with vibration damping: Heat-activated expansion locks the 14 mm shank securely, reducing chatter and tool deflection for longer tool life and better surface finish.

By combining precise concentricity, high-speed stability, and a secure shrink-fit grip, this chuck simplifies tool changes, reduces downtime, and enhances overall machining performance. You gain reliable, repeatable results across jobs, improved surface finish, and confidence in every cut, backed by robust, purpose-built engineering for demanding BT40 applications.
