Starrett No. 829 Small Hole Gages Set

Starrett No. 829 Small Hole Gages Set

These small hole gages are well balanced tools that are ideal for accurately measuring small holes, slots, grooves, and recesses in all kinds of work. The radius on each gage is less than the minimum diameter to be measured, which provides the 2-point contact necessary for maximum accuracy. Rocking the gages into the hole to be measured will guarantee contact at the true diameter.
