Omega’s BT40 Shrink Fit Chuck with G2.5 precision is built for high-speed CNC milling, offering a secure, precise tool-holding solution for 6 mm shanks up to a 160 mm length. Designed for engineers, machinists, and hobbyists who push performance, it enables reliable operation at speeds up to 25,000 RPM and helps maintain consistent accuracy across demanding jobs.

With a G2.5 precision rating, this chuck delivers superior tool concentricity and minimal runout, so every cut stays true to the programmed path. The heat-expanded shrink-fit design grips the tool shank firmly, delivering stability and effective vibration damping to reduce deflection and improve surface finish in a wide range of materials.

• Heat-expanded shrink-fit grip: Clamps 6 mm tool shanks securely through controlled heat, providing a repeatable, vibration-damped hold that reduces runout at high speeds.
• G2.5 precision and concentricity: Achieves tight concentricity and minimal runout for accurate tool paths and consistently smooth finishes on every part.
• Long reach and rigid 160 mm body: The extended length adds rigidity and reach for challenging setups, maintaining reliable performance up to 25,000 RPM.

By choosing the BT40 Shrink Fit Chuck, you gain a dependable, repeatable tool-holding solution that maintains accuracy at high speeds, reduces downtime from runout issues, and supports consistent finishes across production runs. Built for reliability, it helps your shop achieve better yields with fewer adjustments and less rework.
