Achieve sub-micron machining precision, outstanding vibration damping, and effortless tool changes with GARANT Hydraulic Chucks SK Taper Tool Holders. Designed for high-speed CNC milling, reaming, drilling, and finishing operations on machines equipped with DIN 69871 (SK) steep taper spindles, these hydraulic expansion chucks utilize an internal fluid-filled pressure chamber. Tightening a single actuation screw compresses the hydraulic fluid, expanding the clamping sleeve uniformly around the tool shank. This design delivers superior concentricity, dampens cutting vibrations, and significantly extends tool cutting edge life.
