Mitutoyo Bore Gauge Heads

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.

Heads
