Set includes one dial head that fits onto three gauge bodies. Use them to measure the inside diameter of holes and cylindrical bores.

Measure the inside diameter of holes and cylindrical bores, as well as identify out-of-roundness problems.

Find the inside diameter of cylinders and rings.

These calipers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Deep jaws and extra-long measuring ranges make measuring large material easier.
