The Omega Products HSK63A Shrink Fit Chuck combines precise tool holding with a streamlined heat-and-cool clamping process, designed for HSK63A spindles. It securely grips cutting tools with shanks from 3 mm to 32 mm, delivering a uniform clamping force that minimizes tool slip and maximizes rigidity in every pass.

At 120 mm in length and with a G2.5 interface, this chuck provides repeatable positioning and compatibility with high-speed machining up to 25,000 RPM. It’s built to perform in demanding milling environments, helping you maintain accurate tool alignment and consistent cutting performance.

• Uniform shrink-fit gripping: Heating and cooling expands the chuck for a strong, even clamping force that eliminates tool slip and improves rigidity for more consistent cuts.
• Wide shank range compatibility: Accepts tool shanks from 3 mm to 32 mm on HSK63A spindles, allowing you to run a broader set of tools without swapping chucks.
• G2.5 interface and high-speed capability: Provides precise tool positioning and stable performance up to 25,000 RPM for demanding, high-speed milling.

This combination of secure retention and high-speed capability helps you streamline setup, reduce downtime, and achieve reliable, repeatable results across milling tasks. With consistent clamping force and accurate tool seating, you’ll see longer tool life, smoother finishes, and improved productivity in your shop or workshop.
