Bore Micrometers are generally considered the quickest and most accurate form of bore measurement for the shop floor or inspection department. These are available in both Metric and Imperial, with digital or analogue displays. As well as individual units, which will cover a small size range, most manufacturers also offer sets, which will cover a larger range and generally offer better value for money. These sets come in two version, full or partial sets. The full sets will have a measuring head and display for each size, where as the partial set will usually only have one display in the set. The partial sets are a lower cost option, but do not offer the flexibility of a full set.
