Mitutoyo BOREMATIC 568-440-10

Description

The Mitutoyo Borematic LCD Bore Gauge provides both inch and metric readings. This direct-measuring gauge has an absolute linear encoder to reduce measurement error. The LCD display offers quick and error-free measurement reading and the rotatable display unit allows for reading at almost any angle. Three-point contact system detects lobing or triangular form error, and the TiN-coated contact points provide durability and impact resistance.

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.
