The Omega Products HSK63A Hydraulic Expansion Chuck is a precision toolholder engineered for demanding metalworking. With a G2.5 spindle interface and speeds up to 25,000 RPM, it delivers stable, concentric toolholding at high cutting speeds. Its 80mm gauge length supports reliable setup and repeatable performance for a wide range of cutting tools.

The hydraulic expansion mechanism provides consistent gripping force for superior runout control, ensuring tools stay centered under heavy milling loads. An integrated coolant supply aids cooling and chip evacuation, helping maintain surface finish and extend tool life. Built with premium construction, it arrives ready to use with a premium hex key for fast, confident tool changes.

• Hydraulic expansion for precise grip: Delivers uniform clamping force and excellent concentricity, reducing runout and improving accuracy during high-speed machining.
• Integrated coolant and chip management: Active cooling and flushing support longer tool life and better surface finish in demanding milling operations.
• High-speed readiness with easy setup: Designed for up to 25,000 RPM with a G2.5 interface and an 80mm gauge length, providing stable engagement and quick tool changes using the included premium hex key.

This combination delivers repeatable, reliable performance across a range of applications—from precision milling to high-speed production—helping you minimize downtime, improve part quality, and maintain consistent results across shifts and operators.
