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.

FAQ
How does the three‑point head help with blind‑hole measurement?
The three‑point geometry of the MS908.663 automatically centres inside a blind hole, reducing eccentricity and improving repeatability of internal diameter readings.
What level of accuracy and resolution can be expected?
The instrument provides a resolution of 0.005 mm with an accuracy of ±0.005 mm, making it suitable for tight tolerance internal checks in production and workshop environments.
Is the gauge suitable for frequent workshop use?
Yes; the carbide measuring faces and robust mechanical construction are designed for daily inspection tasks and extended service life.
Can this micrometer measure other internal features besides blind holes?
While optimised for blind holes, the instrument can be used for internal diameter checks, recesses and similar internal features where the three‑point contact can seat reliably.
What is included with the instrument on delivery?
The MS908.663 is supplied complete with a protective transport case to protect the gauge during storage and transport.
