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

Use these gauges to 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.

Carbide-tipped jaws provide greater wear resistance and longer life when measuring abrasive or very hard materials.

Move the jaw along the ruler to take inside and outside measurements.

These calipers have a mechanism which allows you to make finer adjustments.
