This gauge set from RS PRO is designed to provide a level of highly-reliable accuracy when measuring the size of a hole.

Containing 185 drill hole gauges, each with a length of 2 inches, this set can measure any hole ranging from 1.3 mm to 4.98 mm in increments of 0.02 mm. This serves to ensure a high level of precision. Each gauge in the set is made from fully-hardened steel (HRC 60-62) for durability. There's a dedicated slot for each drill hole gauge in the box.

This gauge set from the RS PRO range comes with a certificate of accuracy, so you can have full confidence in its reliability. As well as measuring hole size, these gauges can be used to ensure quality via a go / no-go gauge or to calibrate a micrometre.
