Three‑point internal micrometer MS908.670 — self‑centring, 275–300 mm range (Metav IndustryLine)
The Three‑point internal micrometer is a precision analogue instrument for reliable measurement of blind bores in machine construction and toolmaking.
- Self‑centring three‑point head
- Measuring range 275–300 mm
- Interchangeable measuring insert
- Resolution 0.005 mm, accuracy ±0.007 mm
Consistent centring for blind‑hole work that saves time
The instrument’s self‑centring three‑point head guarantees that the measuring contacts align automatically with the bore axis, reducing setup time and minimising operator error. For applications in production or quality control where repeatability matters, this design converts manual handling into a reproducible process. The unit’s standard range (275–300 mm) fits typical medium‑sized bores encountered in fixtures, housings and component assemblies, providing an efficient balance between reach and ease of handling.
Clear analogue reading with industry‑grade precision
Equipped with an analogue graduation that offers a resolution of 0.005 mm and a stated accuracy of ±0.007 mm, the device provides measurable certainty without complex electronics. These specifications correspond with workshop inspection needs where a tactile feel and immediate visual feedback are valued. In practice, the resolution allows fine incremental control during measurement and the accuracy ensures confidence when recording results for process control or acceptance tasks.
Durable measuring faces and modular inserts for long service life
The measuring contacts are furnished with carbide measuring faces, chosen for wear resistance and stable contact geometry under repeated use. The interchangeable measuring insert system permits adaptation to varying bore conditions and simplifies maintenance: inserts can be replaced without extensive downtime, extending the instrument’s operational life and keeping measurement uncertainty low. This modularity supports varied production demands while lowering total cost of ownership.
Workshop‑ready design tailored to machine‑shop workflows
Built as an analogue micrometer in the Metav IndustryLine, the instrument combines straightforward handling with workshop robustness. A compact overall form (length approx. 145 mm) and a three‑point contact principle help to maintain stiffness during measurement, which is crucial when inspecting bores that require high concentricity. The tool is well suited for standard quality control loops and for technicians who prefer a mechanical measuring instrument with clear physical feedback.
