Bore gauges are widely used in workshops, service stations, and other places where finding out exact inner diameters is crucial. For instance, it can be the diameter of a cylinder in an engine being repaired. Over time, a cylinder loses its cylindrical shape, and in order to evaluate the actual wear, a mechanic has to measure the diameters in several points throughout the cylinder's height. You won't do it using a caliper; the most suitable instrument is a bore gauge, as it can protrude into the cylinder bore. Many bore gauges are offered in kits that include a head and interchangeable anvils allowing you to make measurements at different depths.
A resolution scale may be analog or digital, while the size of anvils is important to select the needed measuring range. For deeper holes, a kit may include extension rods, while ball contact points are often made of carbide steel for durability. In our online store, you will find a wide range of bore gauges and internal micrometer holtest kits sourced from such renowned brands as Mitutoyo, Fowler High Precision, and others. These are high quality precision tools enabling you to complete the job in the best way possible.
