The Omega HSK63A Slim Shrink Fit Chuck is a high-speed toolholding solution designed for precision-critical milling on HSK63A spindles. Its slim profile is balanced to G2.5 at 25,000 RPM for stable rotation and reliable grip, and it features a 6 mm clamping diameter with a 120 mm gauge length for precise, repeatable toolholding in compact, high-speed setups.

• Slim, accessible geometry: The slim body clears toolpaths and fits into tight cavities, improving accessibility for intricate milling and reducing setup time.
• High-speed stability and precision: Balanced to G2.5 at 25,000 RPM to minimize runout and vibration, delivering cleaner cuts and longer tool life in demanding materials.
• Rigid shrink-fit clamping for 6 mm tooling: Provides a secure, repeatable grip on small-diameter tools, enabling quick tool changes and consistent performance on busy production runs.

Designed to improve your workflow, the Omega HSK63A Slim Shrink Fit Chuck minimizes vibration, maintains tight tolerances, and supports repeatable results across a range of jobs—from precise contouring to finishing passes. Its slim profile and 120 mm gauge length provide rigidity and easy access, while the durable shrink-fit mechanism and 6 mm tooling grip reduce downtime and tool wear, helping you achieve consistent, high-quality finishes with less rework.
