The Hydrodehn clamping chuck JIS6339ADB 18x90mm BT50 from WTE is a high-precision tool designed for use in various machines. It meets the requirements of the JIS B 6339 standard and features a slim design that allows for easy handling. With an integrated cooling channel and a cone angle tolerance of AT3, this clamping chuck ensures uniform deformation of the expansion sleeve, resulting in a high run-out accuracy of up to 3 μm. The use of a hexagonal cross handle key allows for easy compression of the hydraulic oil, securely and stably clamping the tool shank. The chuck is designed for a maximum speed of 40,000 min-1 and can operate under optimal conditions at temperatures between 20 and 50 °C. With a tensile strength of 1600 to 1800 N/mm² and a hardness of 52 ± 2 HRC, it is suitable for demanding applications.
