Omega Products BT40 Shrink Fit Chuck - G2.5 - 25,000 RPM - 18mm - 160mm Long

The Omega BT40 Shrink Fit Chuck is a precision tool holder designed for BT40 spindles and high-speed machining. It uses a heat-expanded shrink-fit to securely grip tool shanks, delivering exceptional concentricity and minimal runout for consistent, accurate cuts. With an 18 mm shank diameter and 160 mm overall length, it fits a wide range of tooling setups while maintaining balance at high speeds. Its maximum operating speed of 25,000 RPM makes it well-suited for demanding milling and drilling tasks.

Designed for engineers, machinists, and production teams who demand reliable performance in fast, precision work, this shrink-fit chuck provides stable tool engagement and vibration damping. The result is steady cutting conditions, improved surface finishes, and fewer rework in busy shops.

• G2.5 Precision Concentricity: Delivers excellent tool concentricity and minimal runout, ensuring consistent diameter control and accurate results across multiple passes.
• High-Speed Capability: Built to perform at up to 25,000 RPM, maintaining grip and stability for aggressive metal removal with predictable outcomes.
• Heat-Shrink Clamping for Stability: Shrink-fit action uses controlled heat expansion to firmly grip the tool shank, providing vibration damping and reduced deflection for a smoother finish.

By combining precise concentricity, high-speed reliability, and secure shrink-fit clamping, the BT40 Shrink Fit Chuck helps you achieve tighter tolerances, smoother surface finishes, and more consistent results across demanding milling and drilling applications—delivering dependable performance that you can trust on every job.
