Depth Gauges

Depth gauges are precision instruments used to measure the depth of holes, slots, recesses, and steps on machined parts. They are essential for dimensional inspection in CNC machining, tooling, and assembly work, where accurate depth values directly affect fit, function, and overall product quality.

This collection includes mechanical and digital depth gauges with measuring rods and interchangeable probes, as well as depth micrometer styles for higher resolution work. Look for models with a stable reference base, clear scale or display, low measurement uncertainty, and robust construction suited to both metrology labs and shop-floor inspection, from Insize, Ultra, and Mahr.

Commonly used by engineers, production technicians, and QC/QA inspectors in metalworking, precision machining, mold making, and quality departments that require repeatable measurements and dependable verification of critical features.
