Omega Products HSK63A Slim Shrink Fit Chuck - G2.5 - 25,000RPM - 4mm Clamping Diameter - 80mm Gauge Length

Introducing the Omega HSK63A Slim Shrink Fit Chuck — a compact, high-speed toolholding solution designed for precision milling and drilling. Built for HSK63A spindles, it delivers minimal runout and a strong grip in a slim package, enabling intricate work in tight pockets. Balanced to G2.5 at 25,000 RPM, this chuck maintains stability and accuracy while helping extend tool life in demanding environments.

• Slim, accessible design for tight workspaces: The compact body and 80 mm gauge length let you reach narrow pockets and complex geometries without tool interference, improving accessibility and reducing setup time.
• Ultra-low runout and robust shrink-fit clamping: Shrink-fit construction delivers precise tool seating with a strong, vibration-resistant grip on 4 mm shanks, yielding better finish and fewer retouches at speed.
• Precision balance for high-speed stability: Balanced to G2.5 at 25,000 RPM, it minimizes vibration, preserves tool life, and enhances surface finish in demanding, high-speed applications.

By integrating this shrink-fit chuck into your CNC workflow, you can shorten changeovers, tighten tolerances, and achieve consistent results across jobs. The slim profile improves access to tight features, the low runout and secure clamping reduce rework, and the high-speed balance supports faster, more reliable cutting performance—helping you finish projects with confidence and efficiency.
