Omega Products HSK63A Slim Shrink Fit Chuck - G2.5 - 25,000RPM - 4mm Clamping Diameter - 160mm Gauge Length

The Omega HSK63A Slim Shrink Fit Chuck is engineered for high-speed machining where precision, rigidity, and accessibility matter. Its slim profile clears tight work envelopes while delivering a secure, even grip on cutting tools, enabling accurate, repeatable cuts in demanding applications. With a 4 mm clamping diameter and a 160 mm gauge length, this chuck is built for versatility in compact setups.

Balanced to G2.5 at 25,000 RPM, this chuck stays stable under heavy cutting loads, helping minimize vibration, extend tool life, and maintain tight tolerances across a wide range of materials and operations.

• Slim, accessible design: The compact form improves accessibility in tight pockets and complex geometries, reducing setup time and enabling more versatile toolpaths.
• Precision shrink-fit clamping: Shrink-fit mounting delivers a secure, uniform grip on the tool shank, minimizing runout and boosting repeatable accuracy for consistent results.
• High-speed stability: G2.5-balanced at 25,000 RPM provides stable operation with reduced vibration, delivering smoother finishes and longer tool life in demanding milling workloads.

These features translate into real-world benefits: tighter tolerances, faster and more reliable setups, extended tool life, and consistently high-quality finishes across challenging jobs. The slim, robust design paired with precise shrink-fit clamping gives you the confidence to push at high speeds while maintaining precision and productivity on every run.
