Starrett Small-Bore Gauge Sets
Half-Ball Gauge Set
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.
Half-ball gauges are best for flat, shallow areas.
