If ever tasked with the challenge of identifying an HSK tool holder, the following will explain the differences and dimensions of the machine spindle interface (upper portion) of the HSK Holder. These high precision clamping tools are available as heat shrink construction, collet chucks, Weldon shank adapters and arbor adapter options.
