Omega BT40 Shrink Fit Chuck combines precision and stability for high-speed machining. Designed for BT40 spindles, it delivers exceptional tool concentricity with a G2.5 precision rating and supports cutting up to 25,000 RPM. With an 18 mm shank diameter and a 90 mm length, this chuck provides robust rigidity across demanding milling tasks while helping you maintain tight tolerances and consistent finishes.

Utilizing heat-expanded shrink-fit technology, the chuck securely grips the tool shank for improved stability and vibration damping. This stable grip reduces deflection during aggressive cuts and contributes to smoother surface finishes, even when working with challenging materials or high-feed applications.

• G2.5 precision for tight runout: Delivers excellent concentricity and minimal runout, ensuring accurate tool paths and repeatable results across jobs.
• Heat-shrink grip for stability: Shrink-fit clamping uses controlled heat to firmly fix the tool shank, providing a stable cutting experience with reduced vibration.
• High-speed capability with a rugged build: Optimized for up to 25,000 RPM and built to withstand demanding milling cycles, delivering reliable performance over time.

This BT40 Shrink Fit Chuck helps you improve workflow by delivering precise, repeatable results at high speeds, reducing the need for rework and helping you meet tight tolerances with confidence. Its combination of tight concentricity, secure shrink-fit clamping, and high-speed capability makes it a dependable choice for engineers, machinists, and shop technicians striving for consistent finishes and efficient production.
