Mitutoyo 511-921 Bore Gauge

A set of three bore gauges designed exclusively for ID measurement.
Interchangeable anvils for each gauge enable a wide range of diameter measurement.
The dial gauge supplied provides the indication and is attached to a bore gauge as required. High-accuracy measurement is aided by a large grip with a sponge-like structure that reduces heat transfer from the operator’s hand.
Optional extension rods can be attached for measuring inside deep holes.
