Mitutoyo Inside Micrometer – 5–30 mm, 0.01 mm Resolution
This Mitutoyo 5–30 mm Inside Micrometer is a precision internal‑measurement tool designed for accurate inspection of bores, sleeves, bushings, and machined holes. The micrometer features a smooth thimble action, hardened measuring contacts, and crisp graduations for reliable readings.
The 0.01 mm resolution makes it suitable for tight‑tolerance work in machining, toolmaking, and inspection environments. The micrometer covers the full 5–30 mm range using its integrated expanding anvils.
Cosmetic Note: The coating on the barrel has peeled in some areas. This is common with older Mitutoyo internal mics and does not affect the readability of the scale or the instrument’s performance.
