How is a micrometer built?

Precision blind‑hole inspection is facilitated by the combination of a self‑centring three‑point head, carbide measuring faces and an accuracy of ±0.005 mm; order the MS908.663 via Metav Werkzeuge or consult our advisors for specification support. MS908.663 — three‑point internal micrometer with self‑centring head and ±0.005 mm accuracy (Metav IndustryLine) A self‑centring three‑point internal micrometer MS908.663 designed for fast, repeatable measurement of blind holes in workshop and production environments. Self‑centring three‑point measuring head Accuracy ±0.005 mm for repeatable results Carbide measuring faces for long service life Delivered in a protective transport case Precise blind‑hole measurement with minimal operator error The three‑point measuring concept produces a natural centre‑finding action that stabilises the instrument inside a blind hole, reducing eccentricity and operator influence. With an analogue reading of 0.005 mm and an accuracy of ±0.005 mm, this gauge is suited to quality‑critical internal diameter checks where small deviations matter. The vernier‑style scale enables direct mechanical reading without reliance on batteries or electronics, supporting uninterrupted inspections on the shop floor. This combination of mechanical reliability and fine resolution promotes consistent pass/fail decisions during incoming inspection and first‑off checks. Built for demanding workshop use and long‑term repeatability Constructed with carbide measuring faces, the instrument resists wear in daily use and preserves measuring integrity over longer service intervals. The instrument’s physical length of 145 mm and measuring span of 100–125 mm places it in the standard measuring range for general machine‑shop applications, offering a practical balance between reach and rigidity. The robust design and hardened contact surfaces make the micrometer tolerant of routine handling; the supplied protective transport case reduces the risk of damage during storage and transit, keeping calibration stability intact. Practical advantages for process control and inspection routines Using a self‑centring, three‑point internal gauge streamlines internal diameter checks in blind holes, bores and recesses, enabling faster set‑ups at the bench or on the machine. The instrument’s repeatable seating and fine resolution help to reduce scrap and rework by catching dimensional drift earlier in the process. As an analogue instrument it integrates easily into established measurement routines and inspection sheets, while its mechanical simplicity minimises downtime compared with devices that rely on electronics. Typical applications and handling guidance The micrometer is intended for blind‑hole and internal diameter measurements in general engineering, toolroom checks and production quality control. For best results, ensure clean contact surfaces and a stable seating in the bore before taking a reading; the three‑point head will centre itself, but careful alignment reduces measurement scatter. Periodic verification against a gauge block or master ring is recommended to confirm ongoing accuracy and to schedule recalibration when necessary. The instrument’s durability and simple operation make it a practical choice for repetitive internal measurements on ferrous and non‑ferrous components.
