Verify the diameter or threads of machined holes in finished parts; also called pin gauges. Measure hard-to-reach areas, such as internal grooves and slots. Find the inside diameter of cylinders and rings. Confirm your outside or depth micrometers are accurate.

Hole gages help determine the diameter of a hole. While their function is similar to bore gages, they are less precise, much simpler tools that require measurement of a transferred dimension. We offer several varieties of small hole gage sets as well as telescoping gages for larger holes.

SHOP SMALL HOLE GAGES. Small hole gages have either split ball or full ball contacts. Since round ball contacts cannot accurately measure close to the bottom of a hole, split-ball contacts are used instead when this measurement requirement exists.

At Willrich Precision Instrument, we provide both flexible and solid hole location gages which are slotted to right angle increments to assure the location of the thread line, irrespective of the hole dimensions.

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.
