In this video tutorial, viewers learn how to read a micrometer. This tool allows the user to accurately measure components. They have the ability to measure dimensions accurately to within one hundredth of a millimeter. Micrometers are designed with a wide variety of styles and sizes for normal or specialized applications. Micrometers are able to measure the internal or external dimensions of a component. They are the most important basic measuring instrument used in the metal industry. There are 2 types of micrometers revealed in this video, the depth and anvil micrometer. This video will benefit those viewers who are interested in a career of mechanical engineering and would like to learn about micrometers for the future.
