M312.463 Three‑point internal micrometer (87–100 mm) — 0.001 mm resolution, Metav IndustryLine

A three‑point internal micrometer M312.463 engineered for precise measurement of blind holes and internal bores in the 87–100 mm range, supplied with a setting ring and extension for extended reach.

• 0.001 mm resolution
• Three‑point contact for internal bores
• Includes setting ring and extension
• Supplied in protective case

Repeatable, high‑precision internal measurements for production control

The three‑point contact geometry provides a stable and centred measuring interface that reduces measurement scatter compared with single‑point probes; this results in repeatable bore diameter readings across successive checks. With an indication of 0.001 mm and an accuracy of ±0.005 mm, the instrument covers demanding inspection tasks where sub‑millimetre consistency is required. The matt‑chromed scale and vernier contribute to long‑term legibility, while hardened measuring faces protect the contact surfaces against wear, maintaining measurement integrity over time.

Prepared for blind holes and extended‑depth bores

Designed specifically for internal bores, the measuring set includes a setting ring (87 mm) for straightforward calibration and an extension rod set (152.4 × Ø23.5 mm) that increases usable reach for deeper blind holes. This configuration allows secure contact in bore bottoms without introducing tilting errors, so tasks such as quality control of castings or machined housings can be completed without additional fixtures. The combination of three‑point contact and tailored extensions simplifies alignment and reduces handling time during serial inspections.

Workshop‑ready durability and secure transport

Built for the shop floor, the instrument combines protective features and robust construction: the protective case ensures safe transport and storage, while the instrument’s mass and build quality contribute to stable handling during measurement cycles. The matt‑chrome finish on the scale and vernier resists glare and fingerprints, aiding quick, accurate reading under workshop lighting. These design choices reduce incidental downtime and support consistent metrology practice across shifts.

Integrating precise bore checks into inspection workflows

The metrological characteristics make this measuring set well suited to production monitoring and incoming inspection processes: fast repeat measurements with traceable calibration via the supplied setting ring streamline statistical process control routines. The instrument’s specification supports documented quality procedures and facilitates comparison against reference rings or master gauges. For companies seeking a dependable internal measuring solution, the M312.463 fits into established inspection plans without complex adaption.
