M312.162 Three‑point internal micrometer 75–88 mm – carbide measuring faces (Metav IndustryLine)

The M312.162 is a precision three‑point internal micrometer designed for accurate measurement of small bores and blind holes in fine mechanical and workshop environments.

• Three‑point internal measurement 75–88 mm
• Carbide measuring faces for wear resistance
• Mechanical vernier with 0.005 mm resolution
• Supplied in protective case with setting ring

Precision where compact measurement matters

The instrument’s three‑point design gives stable, concentric contact in confined bores, translating to repeatable results even on short depth runs. Classified in the micro range (maximum measuring range up to 100 mm), this format is ideal where stiffness and compactness are paramount. The analogue vernier provides a 0.005 mm reading increment and an indicated accuracy of 0.005 mm, offering a clear, objective basis for quality control in small‑part inspection and toolmaking. Compliance with DIN 863 underlines its suitability for standardised workshop and inspection tasks.

Durable contacts and consistent repeatability

Hard‑facing at the contact points ensures longevity: the carbide measuring faces resist wear and maintain geometry across frequent cycles, reducing the need for premature replacement and minimising measurement drift. The integrated setting ring allows quick verification of the instrument’s span before a measurement run, supporting process control and traceability. The mechanical construction and robust materials mean the tool performs reliably in production and maintenance environments, contributing to reduced rework and improved first‑pass yield.

Ready for workshop use and straightforward care

Delivered in a protective case, the micrometer is ready to be carried or stored safely between uses, while the matt chrome‑plated scale and vernier reduce glare for easier reading under workshop lighting. The design suits both blind‑hole and through‑bore inspection, with the geometry optimised for small bores and precision assemblies. Routine care—keeping the carbide faces clean and lightly oiled after use and checking the setting ring periodically—keeps the instrument within its specified performance range. For specialised requirements, Metav IndustryLine options and accessories such as the noted extensions are available to adapt the tool to particular fixtures or reach conditions.

FAQ

How accurate is the instrument for small‑bore inspection? The M312.162 three‑point internal micrometer is specified with a reading increment of 0.005 mm and an accuracy of 0.005 mm, making it suitable for precise checks in fine mechanical and small‑part production.

Can blind holes be measured reliably with this tool? Yes. The three‑point contact geometry and carbide faces are especially effective for blind‑hole measurement, providing concentric contact and repeatable readings in shallow and medium‑depth bores.

Is this micrometer appropriate for a workshop environment? The compact micro‑range format and robust construction from Metav IndustryLine suit workshop use; the matt chrome finish and protective case make it practical for daily handling and storage.

What maintenance keeps the measuring faces accurate? Keep the carbide faces free of chips and contamination, apply light corrosion protection after cleaning, and verify span with the setting ring before critical measurements to maintain the micrometer’s performance.

Are there extension or accessory options for specialised tasks? Yes. The instrument can be adapted with the listed extensions and uses the supplied setting ring to verify span; for further accessory options consult Metav Werkzeuge.
