What does a small hole gauge measure?

A small hole gauge is specifically designed to measure small diameter holes that are too tight or narrow for a telescoping gauge to fit into. Its structure allows for precise measurement in these confined spaces, ensuring that even the smallest dimensions can be accurately assessed.

This tool operates on the principle of inserting a tapered or adjustable probe into a hole to obtain a reading of the diameter. This makes it especially useful in applications where components have limited access or where the hole dimensions are critical, such as in engine manufacturing or repairs.

Choosing this option highlights its primary function, which is distinctly focused on measuring smaller features that other tools cannot accommodate effectively.
