The Brown & Sharpe TESA 05710065 Veribor Bore Gauge has a range of 50 to 150mm and is accurate to + or - 0.003 mm. It uses a two-point contact to detect form and shape deviations on bores and holes. The low-clearance circular articulation offers high repeatability of measurements. A centering shoe helps to correctly align the gauge into the bore, while tungsten carbide ball measuring tips offer increased wear resistance. The shaft design helps to prevent user hand warmth from affecting the measured result. 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.Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, is headquartered in North Kingstown, RI.What's in the Box?Brown & Sharpe bore gauge with dial 05710065Inspection certificateFitted wooden case
