The Mitutoyo 112 series point micrometer has a pointed spindle and blade anvil for measuring grooves and keyways, a vernier scale in inch units graduated to 0.001” 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 spindle and anvil are made of hardened steel for durability. 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.
