Starrett 569MBXP Tube Micrometre, Plain Thimble, Carbide Faces, 0-25mm Range, 0.01mm Graduation, 9.5mm Min. Hole Size

The Starrett 569 series tube micrometer features a vertical cylindrical anvil for measuring pipe wall thickness and a vernier scale in metric units for measuring precise outer diameter (OD). The Vernier scale on thimble and sleeve is graduated to 0.01mm and has a rust and glare free satin chrome finish. The micrometer is made of high quality tool steel with black enamel finish for protection and durability. The spindle has a micro-lapping measuring surface for accuracy and is made of wear resistance with carbide tip. Micrometers are precision gauges that measure small distances with a calibrated screw. These measurements are translated into large revolutions of the screw, which can then be read from a scale or dial. Micrometers are typically used in manufacturing, machining and mechanical engineering. There are three types of microns: exterior, inside and depth. External micrometers can also be called micrometer calipers and are used to measure the length, width or outer diameter of an object. Internal micrometers are typically used to measure the inner diameter as in a hole. Depth micrometers measure the height or depth of any shape that has a step, groove or slot. The L.S. The Starrett Company manufactures precision measuring tools, measuring and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
