The Omega HSK63A Shrink Fit Chuck is a precision tool holder designed for high-speed milling with HSK63A spindles. At 85 mm in length, it supports tool shanks from 3 mm up to 32 mm, providing a versatile, single-hold solution for a wide range of cutting tools.

Using a controlled heating and cooling process, the chuck expands evenly to insert the tool shank and then grips it with a strong, uniform clamping force. This minimizes tool slippage and maximizes rigidity, helping to extend tool life and improve cutting performance.

• Even, high‑rigidity clamping: The shrink‑fit process expands uniformly for a strong, even grip on the tool shank, eliminating slippage and enhancing rigidity for longer tool life and consistent cutting results.
• High‑speed performance: With a 25,000 RPM maximum, it maintains stable grip and precision at speed, enabling faster cycles and better surface finish.
• Precise, compatible interface: G2.5 interface with HSK63A spindle compatibility ensures accurate tool positioning and repeatable setups across jobs.

By delivering secure retention, repeatable accuracy, and high‑speed reliability, this chuck helps you hit tighter tolerances, reduce scrap, and keep projects on schedule—every setup, every day.
