Tool Holder Taper Gauges
Without a dimensionally correct tool holder taper, it is not possible to ensure a proper spindle/tool holder connection.
Using tool holder dimensional gauges, the taper and other key features can be checked for wear, or new holders can be checked as a part of incoming inspection. In addition, gauges are a necessity when manufacturing tool holders. Units are available for CAT/DIN/BT tapers in basic contact gauges, dial indicator gauges, as well as air gauges. For HSK, we offer dial indicator, electronic, and air gauges.
These gauges are designed to test the quality and precision of the tool holder taper of steep taper DIN, CAT/ANSI, MAS 403-BT, or ISO standards. Specific testing standards for other tapers may also be available.
While the gauges check the precise measurement of the tool holder taper, it is recommended to check the milling spindle-interface dimensions as well. For some kits, adapters can be included as a customized kit for checking both the taper and spindle dimensions. Learn more about milling spindle dimensional checking gauges.
