Sandvik 392.410CGA-100 32 099 a HSK 100 Hydro-Grip Tool Holder, 32 mm Bore, 99 mm Length

The Sandvik 392.410CGA-100 32 099 A is an HSK 100 Hydro-Grip hydraulic tool holder designed for high-precision milling, drilling, and reaming applications. This HSK-A size 100 interface features a 32 mm connection diameter on the workpiece side and a projection length of 99 mm (approximately 4 inches). The Hydro-Grip system utilizes an internal hydraulic bladder filled with fluid that, when compressed by a tightening screw, exerts uniform clamping force around the tool shank to ensure high radial and axial accuracy with a repeatable run-out of less than 0.003 mm (0.0001 inches). The design supports coolant-through capabilities and is engineered for high-speed spindle performance, providing vibration damping and up to three times the clamping force of conventional chucks. The unit is compatible with collets to extend the clamping range and is suitable for rotating applications in machining centers where rigid-tool stability and consistent performance are required. No year of manufacture is available.
