Pistol 3‑Point Internal Measuring Set M312.324.O (6–12 mm, digital, Bluetooth) — Metav IndustryLine

Pistol 3‑Point Internal Measuring Set M312.324.O — a pistol‑style instrument designed for rapid, precise internal measurement of compact bores, supplied as a set with three interchangeable measuring heads for stepwise coverage of the 6–12 mm range

• Pistol‑style internal measuring set, 6–12 mm
• Digital display with mm/inch and hold function
• Bluetooth output for data transfer
• Supplied as a set with three interchangeable heads

Accuracy and stability for small‑bore inspection

The set is engineered for exacting internal measurements in compact components. With a measurement range of 6–12 mm and a resolution of 0.001 mm, the instrument provides fine incremental readings suitable for tight tolerances; the specified accuracy of ±0.004 mm supports reliable pass/fail decisions during quality control. The three‑point internal measuring principle ensures automatic centring inside the bore, which reduces operator‑induced eccentricity and yields a reproducible datum for comparison across production lots. This classifies the tool in the micro range for compact internal gauging, making it ideal where repeatability and small‑size handling matter.

Fast data capture and straightforward operation

Operation is oriented to efficiency: the digital display with ON/OFF, SET, HOLD and mm/inch mode gives immediate feedback, while Bluetooth data output removes manual transcription and speeds integration into inspection logs or SPC systems. The result is fewer recording errors and faster throughput during batch checks. The pistol form factor allows ergonomic one‑hand positioning and quicker cycle times compared with conventional long‑handled internal comparators, supporting smoother inspection routines in busy workshop environments.

Robust set‑up for workshop conditions

Supplied as a practical set — one measuring pistol with three interchangeable heads for the subranges 6–8, 8–10 and 10–12 mm — the package is tailored for small‑part measurement tasks without additional adapters. The design omits ring and extension attachments, which keeps the tool compact and less prone to misalignment. At about 1.62 kg, the complete set is portable yet substantial enough to feel durable in daily use. The build and functional layout favour straightforward handling during repetitive checks and bench inspection, helping to maintain throughput without sacrificing measurement integrity.

Where this measuring set excels in practice

The pistol‑style internal gauge performs particularly well on blind‑hole and through‑hole work in toolmaking, small‑component production and precision assembly. Its suitability for blind‑hole measurement means tight cavities can be checked without special fixtures, and the three‑point contact provides a centred reading even on slightly tapered bores. The modular heads support rapid range changes while preserving the same reference geometry, so inspection programmes for batches with mixed bore sizes can be executed with minimal downtime. For traceable documentation, the digital output simplifies data capture into QA systems and reduces downstream processing time.

FAQ

What measurement range does the set cover?
The set covers a 6–12 mm measurement range; the three interchangeable heads divide that span into 6–8 mm, 8–10 mm and 10–12 mm segments for convenient stepwise checks.

How precise are the readings?
Readings are provided with a resolution of 0.001 mm and a stated accuracy of ±0.004 mm, making the device suitable for fine tolerance inspections and consistent batch control.

Can the instrument measure blind holes?
Yes — the pistol‑style three‑point internal measuring system is explicitly suitable for blind‑hole measurement, allowing accurate centring and reading without special fixtures.

How is measurement data exported?
Measurement values are shown on the digital display (mm/inch) and can be transferred via Bluetooth for direct logging into inspection software or data collection devices.

What is included in the delivery?
Delivery comprises one pistol‑style measuring instrument plus three interchangeable measuring heads; the set does not include a ring or extension.
