Omega Products HSK63A Slim Shrink Fit Chuck - G2.5 - 25,000RPM - 5mm Clamping Diameter - 80mm Gauge Length

The Omega HSK63A Slim Shrink Fit Chuck is a precision toolholding solution engineered for high-speed machining. With its slim profile and HSK63A interface, it delivers exceptional accessibility in tight pockets and complex geometries, making it ideal for engineers, machinists, toolmakers, and shops that demand repeatable accuracy at speed.

Balanced to G2.5 at 25,000 RPM, this chuck minimizes vibration for stable, precise performance. The compact 5 mm clamping diameter paired with an 80 mm gauge length provides a rigid, space-efficient setup that supports demanding milling, drilling, and contouring tasks without sacrificing tool life.

• Slim, 80 mm gauge length for easy access: The compact design keeps the chuck close to the work, enabling access to tight features and deep pockets while maintaining rigid support and reliable clamping.
• Minimal runout with shrink-fit clamping: Shrink-fit application distributes clamping force evenly around the tool shank, delivering superior runout control for better hole symmetry, surface finish, and tool life.
• G2.5-balanced at 25,000 RPM for high-speed stability: Precision balancing reduces vibration at top speeds, improving surface finish, reducing tool wear, and enabling consistent performance across demanding milling operations.

Designed to integrate seamlessly with existing HSK63A spindles, the Omega Slim Shrink Fit Chuck helps you streamline tool changes, reduce rework, and achieve repeatable results across batches. Its robust construction and precise balance translate to longer tool life, fewer downtime events, and more predictable workflows—from roughing to finishing—so your team can hit tighter tolerances with confidence.
