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.

Order the instrument directly via Metav Werkzeuge or consult the team for specification advice. Three-point internal micrometer M312.130 — 6–8 mm with setting ring (Metav IndustryLine) A three-point internal micrometer M312.130 designed for precise measurement of small bores, especially blind holes, in fine mechanical and quality‑control applications. Three-point contact for secure centring Micro-range 6–8 mm for fine mechanical work Matt chrome scale and vernier finish Supplied with setting ring and extension Precision where very small diameters matter The instrument is tailored to the micro range and covers a measurement span of 6–8 mm, which places it firmly in the category for extremely compact workpieces such as watch components, miniature bearings and small bore features. The three‑point contact geometry produces a stable datum in the bore and reduces miscentring, while the specified accuracy ±0.004 mm gives a verifiable tolerance for inspection tasks. This combination of geometry and repeatability means fewer rejected parts and faster go/no‑go decisions on the shop floor. Built for reproducible calibration and handling Calibration is straightforward thanks to the supplied setting ring Ø8 mm, allowing a quick reference check before a measuring session. The instrument features a matt chrome scale and vernier, providing a non‑reflective, durable reading surface with an indicated reading step of 0.001 mm, so analogue vernier interpretation remains precise for experienced users. Delivered in a protective transport case, the gauge and its accessories are protected during storage and transit, supporting reliable reproducibility from job to job. Improves throughput in routine bore inspection As an analogue, vernier‑type gauge the device is robust and immediately usable without electronic dependencies, so repetitive bore checks can be performed quickly and with minimal setup. The included extension rods permit measurement of deeper blind holes and make the tool more flexible across workpieces. The three‑leg measuring head secures contact against the bore wall, reducing operator‑induced variation and helping to shorten inspection cycles — a clear rational advantage when throughput and traceable repeatability matter. Practical applications and workshop guidance This gauge is suitable for fine mechanical workshops, toolmaking and first‑article inspection where small internal diameters must be verified reliably.

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.

FAQ
What accuracy can I expect from digital three-point inside micrometers?
Digital three-point inside micrometers typically deliver an accuracy of ±2 µm and a resolution of 0.001 mm, which is suitable for fine tolerance work in precision engineering.
Can these micrometers measure deep or stepped bores?
Yes. Three-point inside micrometers are specifically designed for bores and through holes; extensions and exchangeable jaws allow measurements in deep or stepped bores, with extension lengths such as 100 mm and 150 mm available.
Which data interfaces are supported by the digital models?
Digital three-point inside micrometers commonly support Bluetooth, USB, RS‑232 and Wi‑Fi, enabling both direct measurement readout and integration into data acquisition systems.
Are there space-saving versions for tight access?
Compact rod-style three-point inside micrometers are made for confined spaces, while pistol-grip versions provide ergonomic advantages for repetitive measurements.
