Starrett Telescoping Gage with One Arm 89-150mm Handle 82mmL Made in USA
The Starrett 229 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. This 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be slightly rocked in the hole being measured to ensure that the tool is on the proper diameter before it is locked and withdrawn.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. 3 1/2"-6"(89-150mm) Range, 3 1/4" (82mm) Handle.
