What is a Bore Gauge?

A Bore Gauge is a term that is used to describe measuring or transfer tools that are used to accurately measure holes.
Telescopic Gauges: These are a set of gauges which are employed to measure a bore’s size. This is accomplished by transferring the internal dimension to a stand –alone measuring tool. Since this type of Gauge is similar to inside calipers and require the user to develop the proper feel in order to get accurate results. These types of gauges are locked by turning the knurled end of the handles in order to exert a small amount of friction on the telescopic portions of the gauge. Once locked, the gauge is inserted in to the bore at an angle, and then slowly brought to align across the hole. After the bore gauge has been withdrawn from the hold, the anvils remain locked to the bore’s dimension and allow the operator to read the measurement of the bore.
