Three-point internal micrometer – analogue three-point internal micrometer, 8–10 mm range, ±0.004 mm accuracy (Metav IndustryLine)

The three-point internal micrometer is an analogue measuring instrument designed for repeatable internal diameter checks of small bores and blind holes in precision engineering and toolmaking.

• 8–10 mm measuring range
• Accuracy ±0.004 mm
• Three-point measuring for blind holes
• Matt chrome-plated scale and vernier
• Incl. setting ring and extension

Precision where space is limited and errors are costly

The compact design concentrates measurement capability into a narrow envelope, delivering ±0.004 mm repeatability in a small form factor. This makes the device particularly effective in quality control loops where space is restricted and component tolerances are tight; the fine vernier reading (0.001 mm) enables confident pass/fail decisions and reduces rework. By using a three-point contact arrangement, the gauge centres itself in the bore and minimises eccentricity, which translates into faster inspection cycles and fewer scrapped parts.

Built for blind-hole inspection and controlled calibration

Engineered specifically for internal measurements, the instrument’s three-point measuring head is tailored to blind-hole applications, providing stable contact even where access is limited. A setting ring is included for in-situ verification and to maintain traceability of measurements, while the supplied extension (50×Ø5.7) increases reach without compromising rigidity. The matt chrome-plated scale and vernier reduce glare and improve legibility under workshop lighting, helping operators obtain consistent readings throughout a shift.

Robust handling and protective transport for shop-floor use

Constructed with a focus on workshop durability, the instrument arrives in a protective case to prevent shock and contamination during storage or transit. The weighing of the unit and its compact length keeps handling straightforward on the production floor, allowing single-operator measurement where applicable. The analogue mechanism combines mechanical reliability with a high-resolution vernier display, delivering a balance of simplicity and fine measurement capability suited to calibration benches and routine inspection stations.

FAQ

What measurements can be taken with this micrometer?
The three-point internal micrometer from Metav IndustryLine is designed for internal diameter measurement of bores and is especially suitable for blind-hole inspection within the 8–10 mm range.

How is repeatability ensured when measuring small bores?
Repeatability is achieved by the three-point contact geometry and fine vernier reading; the Metav IndustryLine three-point internal micrometer centres in the bore and minimises eccentricity for consistent results.

Is calibration equipment included with the instrument?
A setting ring is included for verification and calibration checks, enabling the user to confirm measurement accuracy before and during inspection runs.

Can this instrument be used on the shop floor without additional protection?
Yes; the instrument is supplied in a protective case to prevent damage during transport and storage, while the matt chrome-plated scale improves readability in typical workshop lighting conditions.
