Omega HSK63A Slim Shrink Fit Chuck is a precision toolholder designed for high-speed CNC machining. Built to fit HSK63A spindles, it features a slim 16 mm clamping diameter and a 95 mm gauge length, delivering unobstructed access to tight pockets and complex geometries while maintaining a robust grip.

Balanced to G2.5 at 25,000 RPM, it delivers stable, vibration-free performance at top speeds, reducing runout and boosting tool life in demanding environments.

• Slim, 16 mm clamping diameter for tight access: The compact profile allows easy reach into crowded setups and tight pockets, improving setup speed and visibility while maintaining strong tool retention.
• G2.5-balanced at 25,000 RPM for stable running: Precise balance minimizes vibration and runout at high speed, delivering smoother finishes and longer tool life in demanding machining tasks.
• Uniform shrink-fit clamping for reliable retention: The shrink-fit action applies even pressure around the tool shank, ensuring repeatable gripping force, reduced wear, and consistent accuracy across cycles.

This chuck provides a dependable, high-performance holding solution that streamlines workflows: faster setup in tight spaces, consistent results at high speeds, and longer tool life with reliable retention. Its robust construction and precision balance help you achieve cleaner finishes, tighter tolerances, and fewer tool changes, making it a smart choice for engineers, machinists, and shop floors that demand reliability in demanding applications.
