What tool can provide measurement of depth in a bore or hole?

The depth gauge is specifically designed to measure the depth of holes or bores accurately. It features a precision scale that allows for easy reading of measurements from the surface down to the depth being measured. This tool is particularly useful in machining and woodworking applications, where determining the depth of recesses or holes is critical for ensuring proper fit and function of components.

In contrast, while calipers can measure the overall depth of objects, they are primarily used for measuring external and internal dimensions rather than specific depths. Similarly, feeler gauges are intended for measuring gaps or clearance between surfaces, and micrometers are more suited for measuring small external dimensions with high precision, rather than depths. Thus, the depth gauge is the optimal choice for measuring depth in a bore or hole.
