Omega Products BT40 Shrink Fit Chuck - G2.5 - 25,000 RPM - 10mm - 90mm Long

The Omega BT40 Shrink Fit Chuck is a precision tool-holding solution designed for BT40 spindle systems in high-speed milling. It accepts 10 mm tool shanks and, at 90 mm in length, provides versatile mounting depth for a wide range of milling tasks. This chuck is ideal for engineers, machinists, technicians, and hobbyists who demand consistent accuracy in demanding machining environments.

With a G2.5 precision rating, this chuck delivers excellent tool concentricity and minimal runout, helping you achieve tight tolerances and smooth finishes. It supports up to 25,000 RPM, making it suitable for both aggressive material removal and high-speed finishing. The shrink-fit design uses controlled heat expansion to grip the tool shank firmly, delivering stable, vibration-damped performance that reduces deflection and improves surface quality.

• Ultra-precise concentricity and low runout: G2.5 accuracy ensures consistent alignment, delivering repeatable, high-quality finishes across jobs.
• High-speed stability up to 25,000 RPM: Built to perform reliably at full speed, minimizing chatter and preserving part precision during demanding cuts.
• Heat-shrink grip for secure toolholding: Heat expansion clamps 10 mm tool shanks firmly for a stable, vibration-damped interface that reduces tool deflection.

In practice, the BT40 Shrink Fit Chuck translates into faster, more predictable workflows: fewer reworks due to runout, longer tool life from reduced vibration, and smoother finishes that meet tight spec requirements. Its 90 mm length and 10 mm shank compatibility simplify tool selection and setup in busy shops, helping you maintain consistent performance across a wide range of materials and applications.
