Hole, Drill, Bore, and Wire Gauges
Gauge the situation with a hole, drill, bore or wire gauge. Gauges like these are used for precision measuring, but each type has a slightly different application. Hole and bore gauges are used to measure the interior diameter of a hole, pipe or cylinder. Drill gauges are used to identify drill bit sizes, and wire gauges are used to measure the diameter of a wire. You can also browse our selection of thickness gauges.
