Telescoping Gauges & Sets

0 products

Telescoping gauges and sets are precision tools designed for measuring the internal diameter of bores or holes. By inserting the gauge into a hole and adjusting it with a knurled knob or handle, the telescoping arms expand until the spring-loaded plungers touch the bore's sides. Once locked in position, the gauge is removed, and the measurement between the contacts is taken using an outside micrometer. Ideal for job shops and machine shops, these tools provide accurate measurements without direct reading capabilities or digital displays.
