The Mitutoyo internal micrometers are precise measuring instruments specifically designed for measuring internal diameters in the range of 5 mm to 30 mm. This measuring screw features a fully hardened, ground, and lapped spindle that ensures high durability. The measuring surfaces are equipped with carbide and offer a convex design that enhances measurement accuracy. A ratchet stop mechanism guarantees a constant measuring pressure, resulting in reliable and repeatable results. The satin chrome finish of the measuring surfaces reduces reflections and improves readability, while the neatly engraved measuring drum with black-marked graduations and numbers allows for easy reading. The internal micrometer comes in a convenient case that also includes an adjustment key for easier handling.
