Omega BT40 Shrink Fit Chuck is a precision toolholding solution designed for high-speed machining. With a G2.5 precision rating, it delivers excellent tool concentricity and minimal runout for accurate, repeatable results at speeds up to 25,000 RPM.

Sized at 32 mm with a 100 mm overall length, this BT40 chuck uses a heat-expand shrink-fit design to firmly grip the tool shank. The result is stable performance with vibration damping, helping achieve better surface finish and reduced deflection in demanding milling tasks.

• G2.5 precision for exceptional concentricity: Ensures minimal runout and consistent tool-path accuracy across speeds, leading to reliable, repeatable results in every job.
• High-speed capability up to 25,000 RPM: Maintains rigidity and precision during fast milling, enabling higher material removal rates without sacrificing accuracy.
• Shrink-fit heat-expansion for secure grip: Provides a firm, vibration-damped hold on the tool shank, reducing deflection and improving surface finish during heavy or precision milling.

This combination of precise grip, high-speed performance, and vibration damping offers reliable, repeatable results, lowers the risk of tool slips, and supports consistent finishes across a wide range of machining tasks.
