Check a variety of hole, groove, and slot diameters. Each gauge in these sets has a different measuring range.

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

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.

Measure the inside diameter of cylinders and rings.

With an LCD screen, these micrometers make it easy to read inside diameter measurements taken from cylinders and rings.

Reach into bores to measure the precise size and location of grooves.

The display, markings, and thumb wheel on these calipers are positioned for comfortable left-handed use.

For measuring in and around machines, these calipers won’t be damaged by coolant.

Take inside and outside measurements by moving the jaw along the ruler.

Jaws move only when the thumb lock is depressed.
