Three‑point internal micrometer MS908.669 — self‑centring bore micrometer, 250–275 mm (Metav IndustryLine)
The Three‑point internal micrometer MS908.669 is a self‑centring bore micrometer designed for precision measurement of blind holes in machining and workshop quality control.
- Self‑centring three‑point measurement
- Measuring range 250–275 mm
- Accuracy ±0.007 mm
- Interchangeable measuring insert
Accurate bore measurement where alignment matters
The three‑point design provides a self‑centring contact with the bore, which reduces alignment error and speeds up set‑up when checking blind holes. With a stated accuracy of ±0.007 mm and an analogue reading step of 0.005 mm, the instrument delivers reproducible results for routine quality checks. The mechanical nonius format keeps the workflow straightforward and avoids dependencies on batteries or electronics, supporting continuous shop‑floor operation.
Robust construction for workshop use
Classified within the standard range for workshop micrometres, the device covers 250–275 mm, a span that balances reach and stiffness for typical machine‑shop components. The measuring faces are made of carbide, improving wear resistance when probing machined bores. The interchangeable measuring insert system allows quick replacement of worn or specialised tips, extending the instrument’s service life and adapting it to specific bore geometries.
Practical handling to reduce cycle time
Designed for efficient operation, the instrument’s three‑point geometry centres itself in the bore and thus shortens measurement cycles compared with multi‑step setups. The analogue format is tactile and direct, providing immediate feedback during measurement. Supplied in a protective case for secure transport, the tool is ready for use at different workstations and is dimensioned to be handled easily by one operator for most inspection tasks.
Reliable data for consistent quality control
Used within a production or inspection routine, the micrometer supports fast go/no‑go decisions and reduces rework by providing consistent internal diameter readings. The combination of a defined measuring range, carbide contact faces and an exchangeable insert system means fewer interruptions for maintenance and predictable measurement behaviour over time. The instrument is especially well suited to blind‑hole verification in component production, jig making and fitting operations.
