Three‑point inside micrometer set M312.484 — 6–12 mm, 0.001 mm resolution (Metav IndustryLine)

The Three‑point inside micrometer set 6–12 mm provides a compact, high‑precision solution for measuring internal diameters and blind holes in precision engineering and maintenance.

• 0.001 mm resolution for fine measurement
• Accuracy 0.004 mm for repeatable results
• Designed for blind‑hole measurements
• Supplied complete with setting ring and case

Precision where tight tolerances matter

The three‑point internal gauge delivers a stable contact geometry that converts small positional differences into dependable readings; with a 0.001 mm scale division and a specified accuracy of ±0.004 mm, the instrument is suitable for close‑tolerance internal measurements in production control and toolmaking. The three‑point mechanism centres automatically inside the bore, reducing alignment error and making the set particularly effective for blind holes where calliper or telescopic systems are impractical. This combination of resolution and repeatability supports faster go/no‑go decisions and reduces scrap rates.

Built for workshop use and quick calibration

The set is supplied as a complete kit with a setting ring (8 + 12) and extension rods (100 mm × Ø5.8 mm), enabling rapid configuration across the 6–12 mm measuring range. The matt chrome‑plated scale and vernier resist reflections and wear, maintaining clear legibility under workshop lighting and handling. Supplied in a sturdy transport case, the three‑piece set stays organised and protected during storage or transit. The included setting ring simplifies zeroing and verification on the shop floor, shortening inspection cycles and keeping throughput steady.

Practical integration into quality processes

Compact by design, the 6–12 mm range covers many small‑bore inspection tasks in jigs, mould components and assembly workstations; the light set mass (approx. 1 kg) supports single‑operator handling while preserving measurement stability. Traceable measuring routines benefit from the high resolution and stated accuracy: measurements taken with this instrument are repeatable and can be incorporated into routine in‑process checks or final inspection steps. The Metav IndustryLine origin ensures availability within a broader programme of metrology tools, making it straightforward to standardise gauges across a workshop.

FAQ

What is the smallest increment readable with this set?
The three‑point inside micrometer set offers a readout increment of 0.001 mm, allowing micrometre‑level discrimination for internal diameters.

Is the set suitable for measuring blind bores?
Yes, the instrument is specifically designed for blind‑hole measurements; the three‑point contact ensures reliable centring and measurement in bores that cannot be accessed by external callipers.

How is the micrometer set delivered and stored?
The set is supplied complete in a protective transport case together with a setting ring and extension rods, keeping components organised and protected during storage and transport.

Does the set include calibration or a setting standard?
A setting ring (8 + 12) is included for quick zeroing and verification on the shop floor; this facilitates consistent setup before batch inspections.

Which workshop tasks is the 6–12 mm range best suited for?
The 6–12 mm range covers small‑bore inspections common in toolmaking, mould components and precision assemblies where high resolution and compact handling are required.
