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

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

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

Protect sensitive electronics from damage while you take accurate measurements.

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

Jaws move only when the thumb lock is depressed.

Versatile enough for general checks, these bore gauges have spring-loaded contacts on the end of their probe to expand inside holes.

Inspect a variety of hole sizes with the gauges in these sets. Each has spring-loaded contacts on the probe, which expand inside holes to measure diameter.

Position these gauges snugly within your bore to measure its diameter. Spring tension pushes the gauge’s two telescoping steel contacts against the walls of your bore.

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

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

Use these gauges to measure the inside diameter of holes and cylindrical bores, as well as identify out-of-roundness problems.

No need for other tools to set a baseline diameter—these bore gauges have a built-in micrometer head.

The jaws on these micrometers work like caliper jaws to precisely measure inner diameters.

Measure the inside diameter of cylinders and rings.

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