Starrett 1175Z Calliper Gauge, Pointed Jaw, White Face, 0.375-6" Range, 0.0005" Resolution

Starrett 1175Z Dial Indicator 81-136-1175 Groove Gauge is used for measuring inner diameter (ID) grooves and internal recesses, reads to 0.0005”, has a dial reading of + or - 30 graduations, and a total measurement range of 0.060”. Two sets of interchangeable jaws measure to gauging depths of 1.25” and 2.50”, and three sets of interchangeable contacts are used with 0.375” - 6.00” bore diameters, 0.100” - 0.265” groove depths, and 0.024” - 0.051” groove widths. The moveable gauging contacts have a 1/2” retractable range, are made from hardened steel and have a chrome finish for long life, and flush ends for gauging blind holes. The fixed lower jaw supports the weight of the gauge and the operator’s hands, preventing incorrect gauging pressure and false readings. A fine adjustment screw and lock help provide additional accuracy. Dial indicators, also called dial gauges, dial callipers, and probe indicators, are precision measuring tools used to measure small linear distances and object sizes. The dial magnifies the measurement for readability by the human eye. They are frequently used in manufacturing, laboratories, and other industrial or mechanical fields, and are suitable anywhere a small measurement must be taken and recorded or transferred, such as checking the variation in tolerance of a work piece. Dial test indicators are very similar to dial indicators, except that the axis of measurement is perpendicular to the axis of the indicator. Standard dial indicators measure the displacement along the axis of the indicator. Dial indicators can be analogue, with a mechanical dial, or electronic, with a digital display. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
