A dial bore gauge is a precision tool designed for accurately measuring the internal diameter of bores or holes. It typically consists of a central shaft with two anvils or probes, a dial indicator, and a handle or frame for stability. The anvils are inserted into the bore, and the gauge provides a reading on the dial indicator, indicating the diameter. This tool is widely used in machining, engine building, and automotive industries for quality control and precise fitting of parts. Its strength lies in its ability to provide highly accurate measurements, even in tight spaces or difficult-to-reach areas, ensuring optimal performance and fitment of components.
