A dial bore gauge is a universal measuring instrument which is designed to measure the inside diameter of a working part through relative measurement. A deviation of a bore can be displayed directly through a dial indicator, a micron indicator or a digital micron indicator which is set on the top of a dial bore gauge.when used in conjunction with a micrometer, can give very accurate and precise inside measurements. Used for holes of at least two inches in diameter, they consist of a base that houses an interchangeable anvil that sets the range of the measurement and a small sliding stud that when compressed will give a reading on the gauge or dial portion of the tool. The dial will have a rotating bezel that is rotated to "zero the gauge at the target measurement, which is set by a separate micrometer. Dial-bore gauges are useful in checking for taper or out-of-round conditions in a cylinder bore as well as many other inside machinists measurements

 *A set of spacer rings and anvils are included with the bore gauge

*With High Accuracy Dial Indicator with 0-3mm Range

*Packed in the wooden box or plastic box.
