What tool is used to control the depth at which a countersink enters the work piece?

The depth gauge is specifically designed to measure and control the depth of a countersink as it is being machined into a workpiece. It provides a precise way to set and monitor the depth of the countersink, ensuring that it is consistently accurate according to specifications. This tool is essential in applications where uniformity and precision are crucial, such as when preparing holes for screws or fasteners that require a flush finish with the workpiece surface.

In contrast, while calipers, rulers, and measuring tapes are useful measuring tools, they do not provide the same level of precision for controlling depth in the same manner as a depth gauge. Calipers are better suited for measuring dimensions such as length, width, or thickness, but they are not specifically designed for setting or controlling the depth of machining operations. Rulers and measuring tapes are primarily designed for linear measurements of larger distances and lack the precision and features necessary for accurately controlling the depth of a countersink.
