Omega Products HSK63A Slim Shrink Fit Chuck - G2.5 - 25,000RPM - 3mm Clamping Diameter - 120mm Gauge Length

Meet the Omega HSK63A Slim Shrink Fit Chuck — a precision toolholder designed for high-speed machining. Its slim profile and shrink-fit grip deliver secure tool retention with minimal runout, even at top speeds. It clamps tools with a 3 mm shank and offers a 120 mm gauge length, making it ideal for small-diameter tools and tight work envelopes.

Balanced to G2.5 at 25,000 RPM, this chuck delivers stable, accurate performance, reduces vibration, and helps extend tool life in demanding environments.

• Slim, accessible design: Enables easy access to tight pockets and intricate geometries while maintaining rigidity for precise tool positioning and faster setups.
• Shrink-fit clamping with minimal runout: Delivers near-zero runout and uniform grip along the tool shank, improving concentricity, surface finish, and tool longevity.
• High-speed balance at 25,000 RPM: Provides smooth, vibration-free operation at top speeds, supporting higher feeds and consistent results in demanding applications.

This combination of a compact form, robust shrink-fit grip, and precise balancing helps you achieve tighter tolerances, reduce downtime, and maintain reliable performance across milling, drilling, and finishing tasks.
