Three-point internal micrometer MS908.674 — self-centring, 50–100 mm (Metav IndustryLine)
The Three-point internal micrometer MS908.674 is a self-centring, analogue gauge designed for precise measurement of blind holes and internal bores in fine mechanical and workshop environments
- Three-point internal micrometer for blind holes
- Self-centring contact ensures consistent alignment
- Carbide measuring faces for wear resistance
- Resolution 0.005 mm for fine readings
Accurate internal measurement even in blind holes
The three-point contact mechanism provides a self-centring measuring action that minimises positional error when measuring blind holes and stepped bores. With an analogue graduation of 0.005 mm, the instrument offers repeatable readings suitable for detailed inspection tasks where sub-0.01 mm differentiation is required. The design converts radial deflection into a centralised reading, reducing user-induced eccentricity and enabling faster measurement cycles compared with single-contact probes.
Durable contact faces and stable mechanical construction
Carbide-tipped measuring faces give the gauge excellent wear resistance, keeping tolerances stable over extended use in workshop conditions. The mechanical construction prioritises stiffness and low play, which supports reproducible results across multiple measurements. Where surface finish and hardness vary, the robust contact material helps maintain accuracy without frequent rework or adjustment.
Complete set and accessories for flexible reach
Supplied as a set of four pieces, the package includes setting rings at 62 mm and 87 mm for quick verification and adjustment of the instrument. Extension pieces enabling deeper reach are available up to 150 mm, which allows measurement of recessed or deep blind bores without compromising the centring effect. This combination reduces the need for additional special tooling and speeds up inspection workflows.
Designed for precision workbenches and toolrooms
Classified in the Micro range with a maximum measuring limit of 100 mm, this gauge is particularly suited to fine mechanics, watchmaking and precision component inspection where compact size and high accuracy are essential. The analogue format preserves a direct, tactile measurement experience favoured in quality control loops, while the three-point geometry and carbide faces address longevity and measurement integrity in regular production use.

FAQ
How does the three-point contact improve measurements?
The three-point geometry of the Three-point internal micrometer MS908.674 ensures that the gauge self-centres in the bore, reducing eccentricity and producing more reproducible internal diameter readings than single-contact methods.
Is the instrument suitable for blind holes only, or can it measure through-holes too?
While optimised for blind-hole inspection, the MS908.674 can also be used for internal measurements in through-holes where the three-point centring and carbide faces remain advantageous.
What verification accessories are supplied with the set?
The delivered set contains setting rings at 62 mm and 87 mm for rapid verification and adjustment, supporting a straightforward calibration routine before inspection runs.
Can the gauge reach deep recesses or stepped bores?
Extensions up to 150 mm are available to increase reach; when combined with the self-centring mechanism, these extensions enable accurate measurement of recessed internal features.
What level of durability can be expected from the contact faces?
The carbide measuring faces are specified for high wear resistance, ensuring long-term dimensional stability under regular workshop use and reducing maintenance intervals.
