Product Overview

The Mitutoyo 568-125 is a precision analogue three-point internal micrometer designed for highly accurate bore measurement in the 30–40 mm range. Unlike digital Holtest instruments, this model employs a mechanical dial indicator (0.01 mm graduation) mounted in the head, giving machinists clear, immediate readouts without electronics.

Its three-point, self-centring contact system ensures reliable alignment in the bore, while hardened, titanium-nitride coated measuring pins deliver durability and repeatable accuracy. This tool is a dependable choice for inspection departments, toolrooms, and machinists requiring fine tolerance verification in mid-range bores.
