Starrett 220MXRL-25 Mul-T-Anvil Micrometer, Ratchet Stop, Lock Nut, Carbide Faces, 0-25 mm Range, 0.01 mm Graduation

The Starrett 220XRL Series Mul-T-Anvil Micrometer uses interchangeable anvils to support various measurement requirements and includes a flat and rod anvil and an anvil to provide an anvil. It features a caliper scale in metric units for precise measurements in outer diameter (OD) and a ratchet stop for even pressure during adjustment. The Vernier scale on thimble and sleeve is graduated to 0.01 mm. The micrometer is made of high quality tool steel with a satin chrome rust and glare finish. Spindle is microlised for accuracy and carbide tipped for wear resistance. A knurled ring nut ensures secure locking of the measuring position. Micrometers are precision gauges that use a calibrated to measure small distances. These measurements are translated into large rotations of the , which can then be read from a scale or dial. Micrometers are usually used in manufacturing, machining and mechanical engineering. There are three types of microns: outside, inside and deep. External micrometers can also be called micrometer calipers and are used to measure length, width or outer diameter of an object. Internal micrometers are typically used to measure inner diameter, like in a hole. Depth micrometers measure the height or depth of any shape that has a step, groove or slot. The L.S. 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.
