Three‑point internal micrometer MS908.654 — self‑centring, 16–20 mm range (Metav IndustryLine)
The Three‑point internal micrometer MS908.654 is a precision instrument designed for reliable measurement of blind bores in the 16–20 mm band, combining a three‑point contact head with a compact frame for confined spaces
- Self‑centring three‑point head
- Measurement range 16–20 mm
- Carbide measuring faces (HM)
- Delivered in protective case
Precise bore measurement where space is limited
The three‑point contact design ensures automatic centring inside a blind bore so that the measuring points engage evenly; this reduces eccentricity and improves repeatability compared with single‑point probes. With a defined measurement range of 16–20 mm the instrument falls into the micro class of calipers, making it especially suitable for fine mechanical tasks and small assemblies where controlled measuring force and stable contact geometry are decisive for consistent results. The compact geometry helps to keep torsion low and supports reproducible checks in confined geometries.
Workshop‑grade contact surfaces and durability
Hard‑facing on the contact surfaces gives dependable wear resistance: the carbide measuring faces resist abrasion in routine shop use and extend service life under frequent contact with metal workpieces. The micrometer’s analogue construction avoids batteries and electronic vulnerabilities, favouring simple maintenance and immediate readiness. Supplied in a protective case, the instrument is shielded during transport and storage, supporting reliable deployment across different production stations.
Readability and measurement certainty
The instrument provides a fine reading step alongside a verified accuracy that supports confident decision making. With a display increment of 0.005 mm and an assessed accuracy of ±0.004 mm, the micrometer allows precise comparative measurements and go/no‑go assessments in production and quality control. The three‑point mechanism shortens setup time for successive measurements and reduces correctional effort, which increases throughput without compromising measurement integrity.
Applications, classification and practical benefit
Classified as a micro‑range internal micrometer, the tool is suited to watchmaking, valve seats, small hydraulic components and other blind‑hole checks where a short, rigid measuring system is required. The self‑centring function removes an additional alignment step, while the robust contact material supports mixed workshop environments. As a compact analogue instrument it combines mechanical simplicity with measurement quality, making it an efficient choice wherever repeatable internal diameters must be verified.
