The Omega Products HSK63A Shrink Fit Chuck is a precision tool holder designed for HSK63A spindles. It securely holds cutting tools with shank diameters from 3 mm to 32 mm using a shrink-fit method, delivering strong, even clamping and eliminating tool slippage.

With a 120 mm length and a G2.5 interface for precise tool positioning, plus a maximum speed rating of 25,000 RPM, it is built for high-speed machining and demanding applications, delivering maximum rigidity and improved cutting performance.

• Uniform shrink-fit clamping for maximum rigidity: The heating and cooling process expands the chuck quickly and evenly, allowing tool insertion and then gripping with a strong, even clamping force that eliminates tool slippage.
• G2.5 interface for precise tool positioning: Ensures accurate alignment with the spindle for repeatable, dependable results across operations.
• High-speed readiness up to 25,000 RPM: Designed for demanding, fast-cycle machining while maintaining grip and stability for cleaner finishes and reliable performance.

This shrink-fit chuck helps you achieve secure tool seating, reduces the risk of tool slippage, and supports longer tool life through consistent rigidity. The combination of precise positioning and high-speed capability enables faster cycles, improved finish quality, and more predictable results across your milling and drilling tasks.
