Used Depth micrometers

A depth gauge is a measuring tool used to measure the depth of holes, slots or other recesses. It consists of a screw with a measuring spindle that is inserted into a measuring tube. The measuring spindle is pushed into the recess to be measured by turning the screw, which measures the depth. Depth gauges come in a variety of styles, sizes and measuring ranges. Some have a digital display that allows the measurement to be read quickly and accurately, while others use an analog scale. They are commonly used in metalworking, engineering, woodworking and other industries where it is important to make accurate measurements of the depth of recesses.
