Description

The Omega BT40 Shrink Fit Chuck is a precision tool holder designed for BT40 spindles, delivering secure, repeatable tool holding in high‑speed milling and drilling. It accommodates 12 mm tool shanks and measures 160 mm in length, making it a versatile choice for shops that demand reliable performance and easy integration into existing setups.

Built around a G2.5 precision rating, this chuck provides excellent concentricity with minimal runout, helping tools cut true at up to 25,000 RPM. The shrink-fit design uses heat expansion to grip the tool shank firmly, delivering stability and strong vibration damping for smoother finishes.

  • G2.5 Precision Concentricity: Delivers exceptional tool alignment with minimal runout, ensuring accurate, repeatable cuts and cleaner finishes across demanding milling tasks.
  • High-Speed Performance up to 25,000 RPM: Optimized for tough machining, maintaining stability and precise engagement to reduce cycle times and improve surface quality.
  • Secure Shrink-Fit Tool Grip: Heat-expanded clamping firmly grips 12 mm shanks, providing stable tool engagement, reduced vibration, and consistent tool life in fast‑paced operations.

This BT40 shrink‑fit chuck helps you streamline setup, minimize deflection, and achieve repeatable results from job to job. With its combination of precision, speed capability, and robust clamping, you can boost productivity, improve finished part quality, and rely on dependable performance in both production environments and precision workshops.
