Economy Telescoping Bore Gauge Sets
Spring tension forces two telescoping steel contacts to expand inside the bore; turn the screw to lock the contacts. To find the bore diameter, use a micrometer to measure the distance across the contacts.

Starrett Small-Bore Gauge Sets
Insert into small bores, slots, grooves, and recesses and turn the knob on the handle to expand the contacts. To find the bore diameter, use a micrometer to measure the distance across the contacts.
Full-ball gauges are best for deep bores.
Half-ball gauges are best for flat, shallow areas.
