The Mitutoyo mechanical interchangeable-rod type inside micrometer provides the ability to take a wide range of high accuracy inside dimensions with a single micrometer head. The Mitutoyo interchangeable rod inside the micrometer makes measuring inside dimensions of different ranges of cylinders, rings, and parallel surfaces faster and easier. The micrometer head is constructed with precision, balance, and durability in mind. The sizes of interchangeable rods can be adjusted with spacing collars, and an extension rod allows for measurements of deep bores and holes.
