FIGURE 3.
A depth micrometer, as the name implies, is designed to measure the depth of
holes, recesses, keyways, and so forth. The tool consists of a base with a
micrometer head, Figure 4.
Various length measuring rods can be inserted
through a hole in the micrometer screw. The rod protrudes through the base
and moves as the thimble is rotated.
