Digital three‑point internal micrometer M312.263.S (275–300 mm) — Carbide faces, RB 4 output

The Digital three‑point internal micrometer M312.263.S is a precision instrument for reliable measurement of blind bores in production and inspection environments.

• Digital readout with mm/inch and hold function
• Carbide measuring faces for wear resistance
• Range 275–300 mm for large internal bores
• RB 4 data output for process integration

Precise, traceable measurements with industrial integration

The instrument combines a digital display with a fine 0.001 mm resolution and an overall measurement accuracy specified at ±0.009 mm, enabling tight tolerances to be checked quickly and confidently. The three‑point measuring head centres automatically in the bore, reducing operator influence and improving repeatability compared with single‑point probes. With a dedicated RB 4 data output, measured values are exported directly to process control or SPC systems, which shortens inspection loops and reduces manual transcription errors — a clear efficiency gain for production lines and inspection benches alike.

Robust design for blind‑hole applications and everyday handling

Engineered specifically for blind‑hole measurement, the gauge features carbide measuring faces that resist wear where contact pressure is concentrated. A measuring depth of 140 mm accommodates deep bores, while the instrument’s construction balances stiffness and handling for stable in‑bore seating. The device is supplied in a transport case to protect the tool in transit and storage; note that delivery is made without a setting ring, so traceable setting or calibration accessories should be arranged separately if required. The solid build and thoughtful ergonomics ensure consistent performance across repeated measurement cycles.

Where this instrument adds value in the workflow

The tool is suited to component manufacturers, toolrooms and quality departments that require accurate internal bore data without complex fixtures. Typical uses include inspection of housings, bearing seats and machined assemblies where blind bores are present. The combination of repeatable three‑point contact, digital readout functions (ON/0, mm/inch, ABS, PRESET, HOLD) and live data output supports both manual control checks and automated data collection strategies. Backed by Metav’s supply chain and quality filter in Emmerich, the device arrives ready for integration into existing measurement procedures and inventory systems.

FAQ

How is the instrument best used for blind‑hole measurement?
The digital three‑point internal micrometer centres in the bore by its three contact points, making the M312.263.S especially reliable for blind‑hole checks where fixed‑stop probes are impractical.

What level of accuracy and resolution can be expected?
The instrument provides a resolution of 0.001 mm with an overall accuracy of ±0.009 mm, allowing precise bore diameter assessment suitable for dimensional control tasks.

Is data transfer to inspection software supported?
Yes — the device includes an RB 4 data output for direct connection to process control and SPC systems, enabling automated data capture from the M312.263.S.

Does the delivery include calibration or a setting ring?
Delivery is made without a setting ring; calibration status is provided according to the supplier’s standard procedure and any specific calibration documentation should be requested prior to purchase.

What protections are in place for transport and storage?
The instrument is supplied in a transport case to protect the gauge during transport and storage, ensuring the measuring faces and electronics remain secure.
