Bore Gauge
The bore gauge is a handy tool to measure the internal diameter of holes or bore.
• A bore gauge, typically a dial bore gauge, consists of a base unit with a moveable measuring head on one end.
• The head has spring-loaded contacts that expand to fit the bore’s diameter.
• A dial gauge on the base unit displays the difference between the head’s size and the actual bore diameter.
