Bore gauges measure holes, or bores, in a workpiece. Dial Bore Gauge Mitutoyo 511-207-20 , 0.4 To .74", 0.0005 Mitutoyo Dial Bore Gauge This direct-measuring gauge uses a two-point contact system to detect geometry problems such as ovality and tape, and carbide-tipped contact points offer extended wear and improved abrasion resistance. Pistol-grip bore gauges are used for fast, single-handed operation with repeatable results from one operator to another. Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. Bore gauges can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores. The Mitutoyo 511-205 Dial Bore Gauge for Small Holes has a measurement range of 0., 4 to 0., 75 and a stem outside diameter of 0., 375. 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. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their teeth. Mitutoyo 511-205 Small Hole Bore Gage without Dial Indicator comes with interchangeable anvils made of alloy steel Ideal for measuring the inner dimensions at the bottom of blind bores and holes, this bore gauge features a range of 1.4 to 2.4'' and a high accuracy of 0... Stem outside diameter of 0., 375 nspecton Gauges - Mtutoyo Dal Bore Gauge Bore gauges are typically calibrated with a setting ring and come in two types: simple and direct-measuring. Carbide-tipped contact points for extended wear and improved abrasion resistance
