A bore gauge, also known as an internal micrometer, is a precision instrument used in metrology to measure the inside diameter of a hole, cylinder, or other internal cylindrical surfaces. It consists of a handle, a measuring head or anvils, and a dial or digital display for reading measurements.
The bore gauge is inserted into the hole or cylinder being measured, and then expanded or contracted to make contact with the internal surface. The measurement is then read from the indicator, which typically displays the diameter directly...
