Omega Products HSK63A Shrink Fit Chuck - G2.5 - 25,000 RPM - 20mm - 100mm Long

The Omega Products HSK63A Shrink Fit Chuck is a precision toolholding solution designed for HSK63A spindles. It securely holds tool shanks from 3 mm to 32 mm, enabling fast tool changes with a strong, even grip. The chuck uses a controlled heating and cooling process to uniformly expand the body, allowing the tool shank to be inserted and then clamped with consistent force to maximize rigidity and minimize slip.

With a 100 mm overall length and a G2.5 interface, it delivers precise tool positioning and repeatable accuracy at speeds up to 25,000 RPM, making it ideal for high-speed milling in demanding applications.

• Secure Shrink Fit with Uniform Clamping: The heating/cooling expansion creates a uniform grip across the tool shank, eliminating slippage and delivering consistent tool-to-spindle rigidity for longer tool life and better cutting performance.
• G2.5 Precision Interface: The integrated G2.5 interface ensures precise tool positioning and repeatable runout control, enabling accurate milling and predictable results across jobs.
• High-Speed Ready up to 25,000 RPM: Designed for demanding high-speed machining, delivering stable performance at top speeds for cleaner finishes and faster cycle times.

This chuck helps you streamline your workflow by delivering fast, reliable tool changes, reducing downtime from slipping tools, and maintaining consistent performance across shifts. The robust shrink-fit design and precise interface translate into longer tool life, improved surface finish, and confidence in your setup—whether you’re in a production line, a job shop, or a DIY workshop.
