The Omega HSK63A Slim Shrink Fit Chuck is a high-precision toolholding solution designed for high-speed milling on HSK63A interfaces. It delivers minimal runout and strong, uniform clamping for demanding applications where accuracy matters.

With a 12 mm clamping diameter and a 120 mm gauge length, this chuck stays balanced to G2.5 at 25,000 RPM, providing stable performance, consistent results, and extended tool life in tough materials and tight work envelopes.

• Slim, accessible design: The compact form reduces interference in tight pockets and complex geometries, enabling easier tool seating and faster setup for intricate parts.
• Precise high-speed balance (G2.5 at 25,000 RPM): Low vibration and near-zero runout keep finishes consistent and tools lasting longer, even at full-speed machining.
• 12 mm shrink-fit clamping for uniform grip: Shrink-fit clamping delivers even force around the tool shank, improving rigidity, repeatability, and secure retention under heavy cutting loads.

This chuck helps you complete jobs faster with dependable accuracy. The combination of slim access, precise high-speed balance, and secure shrink-fit clamping translates into cleaner finishes, fewer reworks, reduced downtime, and longer tool life across demanding milling tasks.
