Expert Bore Gauge Set

The Draper Expert Bore Gauge Set is a precision measuring instrument designed for accurately measuring internal diameters and detecting bore irregularities. Ideal for automotive engineers, machinists and precision engineering professionals, this comprehensive set delivers 0.01mm measurement accuracy for precise bore inspection work. This versatile gauge set enables tradespeople to identify tapers and ovality in cylinders, bores and other internal measurements where dimensional accuracy is critical. The complete kit includes a 3mm travel dial test indicator, 55mm extension bar, and twelve measuring rods ranging from 50mm to 105mm, providing comprehensive coverage for a wide range of bore sizes. Four spacer rings (0.5mm, 1.0mm, 2.0mm and 3.0mm) allow fine adjustment and positioning for precise measurement applications. The entire set is display packed in a protective storage case, keeping all components organised and readily accessible for workshop or mobile use. This makes it particularly suitable for automotive diagnostics, cylinder reconditioning work, and quality control applications where bore wear or manufacturing tolerances need verification.
