Which precision measuring tools can be used to measure bore size?

The use of telescoping gauges, outside micrometers, inside micrometers, and dial bore gauges is ideal for measuring bore size due to their design and accuracy.

Telescoping gauges are specifically crafted to capture the internal diameters of bores. They can expand to fit the diameter of the bore and then be measured with an outside micrometer or a dial gauge. Outside micrometers are utilized for external measurements, allowing for a precise reading of the gauge's expansion, which corresponds to the bore size. Inside micrometers are also designed for measuring internal dimensions and can provide high accuracy for smaller diameters. Dial bore gauges offer an excellent means to measure the diameter of a cylinder bore directly, providing a direct reading in a manner that is both precise and easy to read.

In contrast, the other tools mentioned in the other options, such as calipers, rulers, protractors, height gauges, and square tools, are not as specialized for the task of measuring bore sizes. While calipers can be used for general measurements, they lack the precision and specificity required for accurate bore measurement compared to the dedicated tools in the correct answer.
