Three‑point internal micrometer M312.432 — 10–12 mm, 0.001 mm resolution (Metav IndustryLine)

The Three‑point internal micrometer M312.432 is a precision instrument for measuring blind bores in the 10–12 mm range, designed for workshop and inspection tasks where sub‑micrometre readability is required

• 0.001 mm resolution
• Three‑point internal measurement
• Includes setting ring and extension
• Delivered in protective case

Precision built for repeatable bore measurement

The M312.432 combines a 0.001 mm reading with an assessed accuracy of ±0.004 mm, making it suitable where fine tolerance control is required. The three‑point measurement mechanism centres itself within the bore, reducing eccentricity and operator influence compared with single‑point probes. This instrument therefore provides a rational basis for quality decisions: measurable values that can be relied upon for process control and pass/fail assessment.

Designed specifically for blind bore applications

Engineered for blind holes, the micrometer features an extendable probe element (extension 101.6 x Ø5.8 mm) and a dedicated setting ring for quick zeroing and verification. The combination of probe length and compact head allows access into short to moderate blind bores without sacrificing stability. For workshop use this translates into faster inspection cycles and fewer transfers to separate measuring fixtures, supporting efficient throughput and fewer machine interruptions.

Robust finish and practical transport solution

Critical elements such as the matt‑chromed scale and vernier resist glare and aid clear reading under varied lighting. At approximately 0.6 kg, the instrument balances rigidity with manageable handling. Delivery in a protective case protects the instrument during transport and storage, preserving calibration and reducing downtime. The overall construction supports reliable daily use in production and inspection environments, offering both practicality and long‑term serviceability.
