The Mitutoyo 568-463 Borematic LCD Bore Gauge has a measurement range of 0.425 to 0.5" and is accurate to + or - 0.00025". The absolute linear encoder helps reduce error, and the LCD screen offers quick and error-free measurement reading with a 330-degree rotatable unit. Three-point contact system detects lobing or triangular form error and TiN-coated contact points provide durability and impact resistance. Gradient spacing is 0.00005". The gauge has SPC data output for recording and storing measurements on a computer as well as a GO/NO-GO judgment function. Origin point is quickly set with an origin button and the gauge retains this setting for the entire battery life.

Bore gauges measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their teeth. Bore gauges are typically calibrated with a setting ring and come in two types: simple and direct-measuring. Simple bore gauges are used with a caliper to transfer the hole measurement, while the more complex gauges take the measurement directly, and display it through a vernier, dial, or digital display. Bore gauges have a two- or three-point contact, indicating how many points on the gauge head touch the inside of the bore. Two-point contacts are better at measuring ovality, while three-point contacts are used to measure lobing or triangular form error. Pistol-grip bore gauges are used for fast, single-handed operation with repeatable results from one operator to another. Bore gauges can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores.
