Three‑point internal micrometer MS908.673 — self‑centring, 0.005 mm analogue
The Three‑point internal micrometer MS908.673 is an analogue, self‑centring inside micrometer designed for precise measurement of blind holes in fine mechanical and workshop applications
- Self‑centring three‑point measuring system
- Hardmetal measuring faces (carbide)
- Analogue resolution 0.005 mm
- Designed for blind‑hole measurement
Repeatable centring for reliable results
The micrometer’s defining benefit is its self‑centring three‑point head, which aligns reliably in blind bores and reduces off‑axis error during measurement. This design converts operator input into a consistent contact geometry, lowering variance between individual readings and helping to meet process tolerances with fewer rechecks. The analogue graduation with 0.005 mm division gives a clear, immediate view of dimensional changes; when traceable comparability is required, the instrument’s mechanical simplicity supports straightforward in‑house verification routines.
Built for longevity and stable contact
Measuring faces made from carbide (hardmetal) ensure high wear resistance where repeated contact with bore edges would otherwise round or score softer contacts. The harder contact points preserve nominal diameter and shape over long production runs, translating into lower replacement frequency and a steadier measuring baseline. Where repeatability over time matters for quality control, the combination of robust contact materials and the three‑point geometry yields consistent seating in the bore and predictable measurement behaviour.
Practical set composition and extension options
Supplied as a set of four, this analogue internal micrometer covers a practical range for precision blind‑hole work and fast gauge changes between nominal sizes. Extensions are available up to 150 mm, enabling larger or deeper bores to be reached without sacrificing centring performance. The instrument is analogue by construction, making it straightforward to use alongside existing mechanical measuring tools; shops that prefer simple, robust gauges will appreciate the minimal maintenance and easy field adjustments afforded by the setting rings.
Clear advantages in process environments
In repetitive inspection tasks or small‑batch production, the instrument’s self‑centring function reduces operator training time and speeds routine checks. The carbide faces and solid construction lower total cost of ownership by reducing wear‑related drift; together with the fine analogue graduation, these characteristics deliver a balance of durability and measurement fidelity that supports reliable quality control in component manufacture.

FAQ
What measurement range does the instrument cover?
The set covers a 20–50 mm measuring range, supplied as a set of four sizes to allow quick changes between nominal diameters.
Is the micrometer suitable for blind‑hole bores?
Yes — the instrument is explicitly designed for blind‑hole measurements, its three‑point, self‑centring head ensuring reliable seating where standard internal callipers may not centre.
What is the smallest readable increment on the scale?
The analogue nonius offers a 0.005 mm graduation for fine visual readings and repeatable comparison checks.
Are extension rods available for deeper bores?
Extension rods up to 150 mm are available to access deeper or recessed bores while maintaining the self‑centring capability.
