Order the instrument directly via Metav Werkzeuge or consult the specialists for application support and delivery from Emmerich. Three‑point internal micrometer M836.706 — self‑centring, 10–12 mm range A Three‑point internal micrometer engineered for repeatable small‑bore measurement in precision engineering and toolmaking applications. Self‑centring three‑point contact Measuring range 10–12 mm 0.005 mm accuracy Carbide measuring faces Precise small‑bore measurement where repeatability matters The instrument is built around a three‑point contact head that automatically aligns with the bore axis, reducing centring errors and shortening setup time. With a measuring range of 10–12 mm and an indicated accuracy of 0.005 mm (5 µm), the tool closes the gap between standard gauges and specialised micro‑measurement equipment. The analogue spindle gives tactile control for delicate adjustments while the fine graduation supports controlled readings, making this an efficient choice for repeat inspections and small‑batch quality checks. How the self‑centring design reduces operator influence The self‑centring mechanism distributes contact forces across three equally spaced anvils, so the measured diameter is less sensitive to off‑axis pressure or misalignment. This mechanical advantage translates into greater repeatability during serial checks and reduces rework caused by inconsistent measurements. For production environments where cycle time and conformity are measured in minutes, the reduced need for re‑positioning and re‑measuring saves technician time and improves throughput. Hardened measuring faces for durability and consistent results Measuring faces are finished in carbide, providing wear resistance and stable contact geometry over long service intervals. Carbide faces preserve accuracy in workshop conditions where handling and ambient contaminants can accelerate wear on softer surfaces. The combination of hardened contacts and a precise spindle contributes to a long service life while keeping calibration needs predictable, which supports reliable inspection routines in busy maintenance or manufacturing departments. Practical integration into inspection and assembly workflows Compact dimensions and clear analogue feedback make the gauge simple to use at the bench, on assembly lines or in toolrooms. The device is especially suited to fine mechanical work, gauge verification and small‑bore checks in toolmaking, hydraulic components and precision housings. Where instrument interchangeability is required, the three‑point principle ensures consistent centring across different bore geometries, simplifying process documentation and reducing operator training overheads. Care, handling and calibration considerations Routine care is limited to keeping the measuring faces clean and protecting the spindle from shock and contamination. The mechanical nature of the instrument makes field checks straightforward and allows rapid verification against dated master rings or reference gauges. For traceable workflows, the gauge can be incorporated into regular calibration cycles to maintain documented measurement certainty and ensure continued compliance with internal quality plans.

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.
