Description

The Starrett 579 Telescoping Gage is used for determining the true size of holes, slots, and recesses up to 6" (150mm). The ends of both contacts are hardened and ground to a radius to allow proper clearance on the smallest hole the gage will enter. The tool must be slightly rocked in the hole being measured to ensure that the tool is on the proper diameter before it is locked and withdrawn. The final hole size is obtained by measuring over the gage contacts with a micrometer. 5/16-1/2 (8-13mm) Range, 12 (300mm) Handle.

Key Features

It has a slightly larger range and two telescoping contacts compared to no. 229 series

Handle is firmly attached to the contact piston and automatically becomes self-centring

Constant spring tension gives uniform contact pressure

Both pistons are easily locked to any desired setting
