Take advantage of the combination of compact micro‑range measuring, stable three‑point contact and DIN‑compliant vernier control to secure reproducible internal measurements; order the instrument directly via Metav Werkzeuge or request specialist advice from our consultants. Three‑point internal micrometer M312.131 — 8–10 mm range, three‑point contact (Metav IndustryLine) The three‑point internal micrometer M312.131 is a micro‑range measuring instrument designed for accurate internal diameter checks and blind‑hole measurements in precision workshops and small‑part metrology. Three-point contact for stable internal measurement Measuring range 8–10 mm for micro applications DIN 863 vernier scale, matt chrome finish Micro‑range precision where tight tolerances matter The instrument belongs to the micro‑range class (max. 10 mm), making it suited to fine mechanical work where compact geometry and low deflection are crucial. Its three‑point contact system centres reliably in the bore, reducing eccentricity and permitting repeatable results even on short depths. With a stated accuracy of ±0.004 mm, the device provides a clear rational advantage for small‑part inspection: fewer rejects, faster set‑up and confidence when verifying bores for precision assemblies. The M312.131 is therefore appropriate for watchmaking, micromechanics and sample inspection in quality control. Reliable measurement of blind holes and short bores Built specifically to address internal measurements in restricted geometries, the instrument is fitted for blind holes, enabling consistent readings where standard callipers or telescoping gauges struggle. An adjustable ring facilitates fine setting of the contact span for small increments within the 8–10 mm range, so each check can be adapted without disassembly. The three‑point principle spreads contact forces evenly, which reduces deformation of soft components and enhances reproducibility in serial checks. Clear vernier reading and durable scale finish The scale and vernier are matt chrome plated, providing a non‑reflective surface for easy reading under workshop lighting and improved resistance to wear. The vernier offers a fine reading of 0.001 mm, enabling operators to resolve small differences at the micro scale; this enhances process control when aligning parts or setting fixtures. The mechanical construction prioritises a positive tactile feel at the spindle, supporting controlled measuring pressure and consistent operator technique for routine inspections. Workshop suitability and standards conformity Manufactured to DIN 863, the instrument meets recognised metrological conventions for analogue vernier measuring tools and is immediately usable on the shop floor. Its compact body (length 55 mm) and straightforward operation make it a practical addition to bench measurement kits. Supplied in a transport case, the unit is protected for transit and temporary storage — a pragmatic solution when instruments are moved between workstations or taken to inspection points. Metav’s approach to democratising precision ensures that this tool combines established design with workshop‑oriented practicality.

Measure deep bores accurately with three-point inside micrometers
Three-point inside micrometers, also known as 3-point inside micrometers or three-point internal micrometers, are precision instruments designed for accurate internal diameter measurement in bores, through holes and other confined areas. They are available in analogue and digital versions and in several form factors, from pistol-grip models to compact rod-style designs for restricted spaces.
How these micrometers work and where they pay off
The instrument uses three symmetrically arranged measuring tips that expand to contact the bore surface, delivering a stable centre reference and reducing sensitivity to positional error. This makes three-point inside micrometers indispensable for inspection of multi-step bores, precision components and routine quality control in production and workshop environments. Digital variants offer incremental and absolute measuring modes, presets and direct data transfer, while analogue models retain robust simplicity where a no-frills solution is preferred.
Clear benefits that improve throughput and quality
- Reduced rework and faster setup thanks to the three-point contact geometry, which centres automatically and minimises alignment errors.
- High measurement precision with digital models offering ±2 µm accuracy and a resolution of 0.001 mm, supporting tight tolerance control.
