Precision inside measurements for tight bores and through-holes
Three-point inside micrometers, also known as inside micrometers and bore micrometers, provide highly accurate internal measurements for bores, through-holes and other confined areas, enabling reliable diameter and form checks during metalworking. These instruments are available in pistol-grip and compact rod designs, with analogue models featuring verniers and option to fit a dial gauge, while digital versions offer resolutions down to 0.001 mm, data outputs such as USB or RS-232 and advanced functions like absolute and incremental measuring. Accessories such as interchangeable anvils and extensions (100 mm and 150 mm) expand reach into deep bores, and models with microcomputer control even support wireless data transfer for streamlined process integration.

6-12mm Three-Point Internal Measuring Gun Set With 3 Interchangeable Heads, Digital Display Bluetooth - Metav IndustryLine
The compact digital set combines quick handling, reliable three‑point centring and high resolution for consistent bore inspection; the pistol‑style internal measuring set delivers repeatable readings in the 6–12 mm band and simplifies data capture with Bluetooth. Order the Pistol 3‑Point Internal Measuring Set directly via Metav Werkzeuge or ask our consultants if needed. 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.

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.
- Flexible data handling: Bluetooth transmission to a computer, smartphone or tablet over almost 50 metres, plus USB, RS-232 and Wi‑Fi interfaces for seamless integration into inspection workflows.
- Adaptable measuring range through exchangeable jaws and extensions available in 100 mm and 150 mm lengths, enabling measurements in deep bores.
- Ergonomic options such as pistol-grip variants for comfortable repeat measuring and compact rod designs for confined spaces.
