Omega Products BT40 Shrink Fit Chuck - G2.5 - 25,000 RPM - 32mm - 120mm Long

The Omega BT40 Shrink Fit Chuck is a precision tool holder designed for BT40 spindles, built to deliver secure, concentric tool clamping in high‑speed machining. With a G2.5 precision rating and a maximum operating speed of 25,000 RPM, it provides accurate, repeatable results even under demanding cutting conditions.

The shrink‑fit design uses controlled heat expansion to firmly grip the tool shank, offering exceptional stability and vibration damping. This helps minimize tool deflection and supports a smoother surface finish, so you can trust consistent performance through long runs and challenging cuts.

• G2.5 Precision Concentricity: Ensures excellent tool concentricity and minimal runout for accurate, repeatable machining results at high speeds.
• Shrink‑Fit Stability with Vibration Damping: Heat‑expanded clamping delivers a secure grip on the tool shank, reducing vibration and deflection for steadier cuts and better finish.
• High‑Speed Capability with a 120 mm Body: Designed for up to 25,000 RPM, with a long 120 mm length that provides versatile mounting and reach for a wide range of applications.

This BT40 shrink‑fit chuck is a reliable choice for shops needing precise toolholding that can keep up with fast, demanding workflows. By delivering consistent concentricity, stable tool engagement, and high‑speed capability, it helps you achieve repeatable part quality and a smoother, more efficient machining process from setup to finish.
