The Omega BT40 Shrink Fit Chuck is a precision toolholding solution designed for high-speed CNC machining. It accommodates 12 mm tool shanks and measures 90 mm in overall length, delivering a compact, rigid interface for demanding milling and drilling tasks.

With a G2.5 precision rating, it delivers excellent tool concentricity and minimal runout, helping you achieve consistent results even at top speeds. The shrink-fit design uses heat expansion to firmly grip the tool shank, providing outstanding stability and vibration damping to reduce deflection and improve surface finish.

• G2.5 Precision Concentricity: Ensures tight runout for accurate, repeatable cuts and smoother finishes at high speeds.
• Secure Shrink-Fit Tool Grip: Heat-assisted clamping on 12 mm shanks creates a stable, vibration-damped interface that resists deflection.
• High-Speed Capability: Engineered for up to 25,000 RPM, enabling fast material removal with consistent performance.

Together, these features deliver a reliable, ready-to-use toolholding solution that improves workflow and part quality. The tight concentricity reduces finishing errors, the secure shrink-fit grip minimizes tool movement under load, and the high-speed capability supports efficient production with fewer rework cycles. Built for durability and repeatable performance in busy shops, this chuck helps you achieve consistent results across demanding applications.
