Bore & Hole Gauges
Bore and hole gauges measure the internal diameter of holes. The range includes bore gauges in dial and digital versions, and telescoping gauges. Telescoping gauges transfer a size, while dial and digital types read the size directly.
Machinists, engine builders and inspectors use them where the diameter and its variation along the hole matter. Consider the bore range, the depth that must be reached, the resolution, and whether a master ring or micrometer is needed to set the gauge.
