Mitutoyo 107-205 Outside Micrometer with Dial Indicator, 100-125mm Range, 0.01mm Graduation, +/-0.003mm Accuracy

The Mitutoyo 107 series outside micrometer is for use with an optional dial indicator for Go/No-Go (GO/NG) tolerance inspection (sold separately). It also has a vernier scale in metric units for taking precise outside diameter (OD) measurements, and a ratchet-stop mechanism for uniform pressure during adjustment.
The micrometer’s frame has a baked enamel finish for protection and durability. The vernier scale on the thimble and sleeve is graduated to 0.01mm, with a satin chrome rust- and glare-resistant finish. The anvil retracts by means of a trigger for quick workpiece insertion and release. The spindle and anvil have flat measuring faces and are carbide-tipped for wear resistance. A spindle lock helps provide secure locking of the measurement position. The micrometer comes with a plastic case for storage.
Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
