Insize 2425 Bore Gauges For Small Holes
The Insize 2425 Bore Gauge series is designed to measure the diameter of small holes with a level of precision that standard bore gauges can't reach. Each gauge in the series features a carbide contact point and anvil for long-lasting wear resistance and consistent readings, and the series spans a wide selection of ranges from as small as 8mm up to roughly 20mm (with inch-equivalent models such as the 2425-E6, 2425-E8, 2425-E12, and 2425-E20) making it a practical choice for machine shops, tool and die makers, and quality control labs working with small bores, bushings, and precision-machined components. Each gauge is designed to work with a dial indicator or dial comparator to complete the readout, giving you the flexibility to pair the gauge head with the resolution your application demands.
