Corochuck 930-HA10-HD-25-106, Sandvik Coromant, HSK 100, 25mm Bore, <4ΜM Run-Out, Through-Coolant.

The Sandvik Coromant Corochuck 930-HA10-HD-25-106 is a heavy-duty, high-precision hydraulic tool holder featuring an HSK 100 (HA10) machine-side coupling. Designed for milling, drilling, and reaming operations, it utilizes fulcrum technology with a brazed membrane to provide high clamping force and pull-out security. This model specifies a 25mm bore size (hole diameter) and is engineered to eliminate vibration for increased stability and improved surface finish. The system supports high-precision repetition with a run-out tolerance of less than 4 μm at 2.5 × DC. It includes an adjustment screw for setting clamping length and is balanced according to DIN 69888. This specific unit comes with a collet and is compatible with shrink-fit tooling. The machine-side coupling is ground to ensure precision, and the hydraulic mechanism allows for quick tool changes using a torque wrench without the need for external equipment. Through-coolant capability is supported to enhance performance in demanding metalworking applications. Year of manufacture is not available.
