The Omega HSK63A Slim Shrink Fit Chuck is a precision tool holder designed for high-speed machining. With a slim, accessible profile and the proven HSK63A interface, it delivers shrink-fit retention that minimizes runout and maximizes rigidity for intricate work.

Balanced to G2.5 at 25,000 RPM, this chuck remains stable at high speeds, reducing vibration and supporting consistent seating, longer tool life, and reliable finishes across demanding applications.

• Slim, accessible geometry: The compact profile improves clearance around complex parts and fixtures, enabling easier tool changes in tight work zones without sacrificing rigidity.
• High-speed balance and robust clamping: Engineered to a G2.5 balance at 25,000 RPM for smooth operation, reduced chatter, and longer tool life in demanding cycles.
• 10 mm clamping diameter with 120 mm gauge length: Secure retention for standard 10 mm tooling with a generous gauge length for stable, repeatable seating and alignment.

This shrink-fit chuck translates into faster setups, tighter tolerances, and more repeatable results across jobs. The combination of slim geometry, precise balance, and secure clamping reduces chatter and wear, delivering consistent finishes and lowering downtime in busy production environments.
