What tool is used to measure the depth of an item?

The depth gage is specifically designed for measuring the depth of holes, slots, and other recesses in various materials. It typically features a long, straight measuring blade that can be inserted into the material, allowing for precise depth readings. This tool provides a clear and accurate measurement, which is essential in tasks requiring depth assessment.

Other tools, although useful for measurements, do not serve this specific purpose as effectively. A caliper can measure depth to some extent, but it is primarily intended for measuring external and internal dimensions and might not provide the same level of accuracy as a dedicated depth gage. A micrometer is designed for high-precision measurements of external dimensions, making it unsuitable for measuring depths. A scriber is primarily a marking tool used for creating precise lines or marks on materials but does not measure depth.
