The Omega HSK63A Shrink Fit Chuck is a high-precision toolholding solution designed for HSK63A spindles. It securely clamps tool shanks from 3 mm to 32 mm, delivering a rigid, slip-free interface for demanding milling operations.
Using a controlled heating and cooling cycle, the chuck expands to accept the tool shank and then contracts to grip with even clamping force, maximizing tool life and cutting performance.

• Secure, uniform tool grip: Expands evenly to clamp shanks from 3 mm to 32 mm, eliminating slippage and providing maximum rigidity for consistent cuts and longer tool life.
• High-speed compatibility: 25,000 RPM maximum enables fast machining with controlled runout, ideal for high-speed milling and finishing tasks.
• G2.5 precision interface: Delivers repeatable, accurate tool positioning with the spindle, improving process stability and part-to-part consistency.

This combination of shrink-fit clamping and a precise G2.5 interface translates to faster setups, fewer tool changes, and reliable results across a wide range of milling applications. You’ll experience cleaner finishes, reduced chatter, and improved overall performance when working with hard materials or precision features, thanks to the rigid, uniform grip and stable tool alignment.
