Telescoping Gauges The Telescoping Gauge Set is a precision measuring tool designed for measuring internal diameters of holes, bores, and widths of slots. The gauge transfers the internal dimension, which is then accurately measured using an outside micrometer. This method provides reliable and accurate internal measurements in machining, manufacturing, automotive, tool room, and inspection applications. Supplied as a complete set of six gauges, the Telescoping Gauge Set covers a wide measuring range and is ideal for measuring bores, recesses, grooves, and internal dimensions that are difficult to measure directly.
