Telescoping Gages
Starrett telescoping gages are 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
These tools 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the tool is on the proper diameter before it is locked and withdrawn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
