Description Condition: New Old Stock (NOS) – unused, but stored for some time. Supplied in its original fitted wooden box, complete with a used Mitutoyo 0.01 mm dial gauge already mounted. Wooden box shows light storage wear, but the instrument itself is in excellent condition and operates smoothly.Used 35mm Set ring supplied Product Overview The Mitutoyo 568-125 is a precision analogue three-point internal micrometer designed for highly accurate bore measurement in the 30–35 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.
