Internal Micrometer Set M312.172 — carbide measuring faces, 2–3 mm range (Metav IndustryLine)

The Internal Micrometer Set M312.172 is a precision mechanical kit designed for reliable internal diameter measurement of fine bores and blind holes in confined workpieces.

• Carbide measuring faces for wear resistance
• Measurement range 2–3 mm for fine bores
• Supplied with 2.5 mm setting ring and extension
• Mechanical micrometer set, accuracy ±0.004 mm

Precision where small tolerances matter

For tasks that demand repeatable results in minimal diameters, this set offers a focused solution. The instrument covers a 2–3 mm measuring range and provides a resolution of 0.001 mm together with an accuracy of ±0.004 mm, enabling trustworthy checks on small bores. Carbide measuring faces grant long-term abrasion resistance, so calibration intervals remain stable and wear-related drift is reduced. This combination suits inspection benches and precision toolrooms that require consistent verification of miniature features.

Engineered to reduce measurement variability

The mechanical design and matt‑chromed scale with vernier support clear readings and stable contact conditions. Included is a 2.5 mm setting ring and an extension that facilitate calibration and transfer of reference values to the workpiece, improving throughput in repetitive checks. The robust construction and measurable mass of the set contribute to steadiness during measurement cycles, while the carbide contact surfaces preserve geometry under frequent use. Together, these attributes help to maintain reproducibility in inspection routines.

A practical kit for fine internal measurement

Delivered as a two‑piece set, the instrument is optimised for confined bores and blind‑hole applications, where conventional callipers cannot reach or centre reliably. The set format simplifies workshop logistics: each piece complements the other for incremental checks and cross‑verification. Built for precision environments, the set is suitable for micro‑mechanical work, toolmaking and quality control tasks where small diameters and high repeatability are routine. Metav IndustryLine’s focus on accessible precision ensures that the components meet professional expectations on durability and handling.
