Product details:

Calliper-type jaws for making inside dimension (ID) measurements Vernier scale in metric units for taking precise inside dimension (ID) measurements Locking clamp to hold measurements in place Satin chrome finish helps resist rust and reduce glare Carbide-tipped measuring faces helps provide wear resistanceThe 145 series vernier inside micrometre has calliper-type jaws and a vernier scale in metric units for making precise inside dimension (ID) measurements. The micrometre is made of high-grade tool steel for durability and has a satin chrome rust- and glare-resistant finish. The measuring faces are carbide-tipped for wear resistance. The vernier scale is graduated to 0.01mm. A locking clamp helps hold measurements in place. The micrometre comes with a fitted case for storage.Micrometres 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. Micrometres are typically in manufacturing, machining, and mechanical engineering. There are three types of micrometre: outside, inside, and depth. Outside micrometres may also be called micrometre callipers, and are to measure the length, width, or outside diameter of an object. Inside micrometres are typically to measure interior diameter, as in a hole. Depth micrometres measure the height, or depth, of any shape that has a step, groove, or storage.Micutoyo 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.
