Omega Products HSK63A Hydraulic Expansion Chuck (Form AD) is a high-precision toolholding solution designed for demanding metalworking and high-speed machining. With a G2.5 spindle interface, 12mm tool shank capacity, and an 80mm gauge length, it delivers secure, concentric tool retention at speeds up to 25,000 RPM.

Engineered for engineers, machinists, and shops that value accuracy and efficiency, this hydraulic chuck provides maximum gripping force with minimal runout. Its internal coolant supply helps maintain chip clearance and consistent temperatures, supporting steady performance and reliable finishes even on longer runs.

• Hydraulic expansion for maximum grip and concentricity: The hydraulic actuation evenly expands around the 12mm tool shank to secure tools with minimal runout, delivering precise machining at speeds up to 25,000 RPM.
• HSK63A interface with G2.5 compatibility: Optimized for modern high-speed spindles, offering stable retention and reliable performance across a wide range of cutting tools.
• Internal coolant system and durable build: Built-in coolant channels improve chip removal and tool cooling for consistent surface finishes, while premium materials and precise machining ensure long service life; includes a premium hex key for quick setup.

This toolholding solution helps you streamline production by reducing setup time, preventing tool slippage, and delivering repeatable results at high speeds. With strong concentricity and effective cooling, you’ll achieve tighter tolerances, smoother finishes, and longer tool life, even in demanding applications.
