EPB 5831 chucks use high pressure and a single pressurised screw to grip small-diameter cutting tools uniformly. According to Seco, this results in runout of less than 5 micron at 3xD.
The chucks accommodate 6, 8, 10 and 12 mm tool diameters and, by using reduction sleeves, can hold various shank types and diameters. For example, with a sleeve, the 12 mm hydraulic chuck can hold 3, 4, 5, 6, 8 and 10 mm tools.
EPB 5831 chucks are available in HSK-A63, HSK-A100, BT 40 and Seco-Capto C5 spindle interfaces.
