Dial bore gauges

Dial bore gauge is an instrument used for measuring ovalization and conicity and for control of internal diameters of circular holes.

This tool consists of a rod with chrome insulating grip; it is provided with dial gauge and a series of interchangeable extensions, with the aim of covering all possible diameters measurements at different depths.

The operating principle is constituted by dial gauge coupled to a mechanical system, which transforms the translation movement of dial gauge rod in a movement of two probes in opposite directions on a plane perpendicular to that of the dial gauge rod.
