About Bore Gauges

A bore gauge is a measuring device for determining the internal size of a hole, cylinder, or pipe. They can give exact readings by inserting the base of the bore gauge into the opening and moving the base gently until it exactly fits the diameter of the hole.

Instruments available include dial and digital gauges with different base configurations.
