Heads for Mitutoyo Electronic Bore Gauges
Swap the head on your electronic bore gauge for one with a different measuring range. Or replace your lost or damaged head with a new one. With three contact points, these self-centering heads measure the average bore diameter and detect out of roundness. They’re more accurate than heads with two contact points.
An adapter (sold separately) is required for Mitutoyo 568 series gauges.
