Omega HSK63A Slim Shrink Fit Chuck is designed for high-speed milling where access and precision matter. It clamps 18 mm tooling with a 120 mm gauge length, delivering strong, uniform grip and minimal runout up to 25,000 RPM, with balance tuned to G2.5 for steady, accurate performance.

• Slim, accessible design: The slim profile provides enhanced access to tight work areas and intricate features, reducing interference and enabling faster, more repeatable tool changes.
• G2.5-balanced at 25,000 RPM: Precise balance minimizes vibration, improves surface finish, and helps extend tool life in demanding high-speed applications.
• Strong shrink-fit clamping (18 mm, 120 mm): Delivers reliable, uniform grip for tools up to 18 mm with a generous 120 mm gauge length, supporting versatile setups and consistent seating.

This chuck helps you streamline production by delivering stable performance across challenging milling tasks. The combination of a slim body, precise high-speed balance, and robust clamping means fewer interruptions, tighter tolerances, and smoother finishes — enhancing overall workflow, cycle times, and tool life in demanding machining environments.
