The Omega HSK63A Shrink Fit Chuck is a precision toolholding solution designed for CNC milling with HSK63A spindles. It securely grips tool shanks from 3 mm to 32 mm through a controlled heating and cooling process, delivering uniform clamping force and maximum rigidity for stable, accurate cuts. Its 160 mm length and G2.5 interface support high-speed work up to 25,000 RPM, helping you extend tool life and achieve smoother surfaces.

• Uniform Shrink-Fit Clamping: The heating and cooling cycle expands the chuck evenly, then grips the tool shank with a strong, uniform clamping force to prevent slip and maximize rigidity for consistent, reliable results.
• G2.5 Precision Interface: Provides repeatable tool positioning and accurate seating, reducing setup time and ensuring consistent runout across jobs for dependable performance.
• High-Speed Capability with 160 mm Length: Engineered for up to 25,000 RPM, delivering stable, high-speed cutting performance while the 160 mm length offers added support and versatility for longer tools and demanding applications.

This shrink-fit chuck helps you improve workflow by delivering secure tool retention, reducing downtime from tool slippage, and providing predictable accuracy across shifts. Its robust design and high-speed capability empower you to tackle challenging materials with confidence, achieving better surface finishes, longer tool life, and more consistent results in a wide range of milling tasks.
