Spindle taper gauges are used to check for worn tapers on machine spindles, as well as for verification when regrinding or manufacturing spindle tapers. As with tool holders, a correctly made and non-worn taper is critical for a strong connection between spindle and tool holder. Units are available for CAT/DIN/BT taper in basic contact gauges, dial indicator gauges, as well as air gauges. For HSK, we offer dial indicator, electronic, and air gauges.
