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.

Combined with the 200–225 mm measurement span, this design delivers repeatable internal diameter checks on medium‑sized components, making the tool suitable for batch inspection or set‑up control. The instrument’s construction focuses on consistent contact geometry, which directly reduces rework and speeds up quality decisions. Durable contact surfaces and controlled measuring force Wear resistance is ensured by carbide measuring faces, which keep measuring geometry intact even under frequent use. The integrated ratchet stop enforces a uniform measuring force, eliminating a common source of operator error and improving consistency between readings. Together these features support higher throughput with fewer rejects, since each measurement is taken under the same mechanical conditions and with long‑term dimensional stability. Clear scales and practical handling for workshop use A matt‑chrome scale and vernier improves contrast under shop lighting and resists reflection, aiding fast reading of the nonius. With a fine reading 0.005 mm and accuracy ±0.008 mm, the instrument bridges the gap between routine workshop control and high‑precision verification. The design includes a deep measuring capability—measuring depth 140 mm—so inner features and deeper bores can be accessed without auxiliary extensions. Supply, set‑up and workshop integration The micrometer is supplied ready for workshop use in a transport case and is delivered without a setting ring; this should be considered when integrating into a calibration routine or fixed inspection station. The analogue format with vernier is straightforward to use where digital outputs are not required, and the robust material choices keep maintenance cycles short.

Yes, the tool is fitted with carbide measuring faces, which resist wear and give stable contact behaviour during serial inspections. Is the micrometer self‑centring and how does that help? The self‑centring three‑point system centres automatically within the bore, reducing alignment effort and improving repeatability compared with two‑point setups. How is the instrument delivered for safe handling? The micrometer is supplied in a protective transport case (plastic or wooden), which simplifies storage and transport between inspection points.

250-275mm Three-Point Internal Micrometer Self-Centring Interchangeable Spindle, 0.007mm Accuracy, Supplied in Case - Metav IndustryLine
Combine reliable self‑centring measurement with a 250–275 mm measuring range and interchangeable measuring inserts for consistent, repeatable bore checks; order the instrument directly via Metav Werkzeuge or consult their specialists for application advice. Three‑point internal micrometer MS908.669 — self‑centring bore micrometer, 250–275 mm (Metav IndustryLine) The Three‑point internal micrometer MS908.669 is a self‑centring bore micrometer designed for precision measurement of blind holes in machining and workshop quality control. Self‑centring three‑point measurement Measuring range 250–275 mm Accuracy ±0.007 mm Interchangeable measuring insert Accurate bore measurement where alignment matters The three‑point design provides a self‑centring contact with the bore, which reduces alignment error and speeds up set‑up when checking blind holes. With a stated accuracy of ±0.007 mm and an analogue reading step of 0.005 mm, the instrument delivers reproducible results for routine quality checks. The mechanical nonius format keeps the workflow straightforward and avoids dependencies on batteries or electronics, supporting continuous shop‑floor operation. Robust construction for workshop use Classified within the standard range for workshop micrometres, the device covers 250–275 mm, a span that balances reach and stiffness for typical machine‑shop components. The measuring faces are made of carbide, improving wear resistance when probing machined bores. The interchangeable measuring insert system allows quick replacement of worn or specialised tips, extending the instrument’s service life and adapting it to specific bore geometries. Practical handling to reduce cycle time Designed for efficient operation, the instrument’s three‑point geometry centres itself in the bore and thus shortens measurement cycles compared with multi‑step setups. The analogue format is tactile and direct, providing immediate feedback during measurement. Supplied in a protective case for secure transport, the tool is ready for use at different workstations and is dimensioned to be handled easily by one operator for most inspection tasks. Reliable data for consistent quality control Used within a production or inspection routine, the micrometer supports fast go/no‑go decisions and reduces rework by providing consistent internal diameter readings. The combination of a defined measuring range, carbide contact faces and an exchangeable insert system means fewer interruptions for maintenance and predictable measurement behaviour over time. The instrument is especially well suited to blind‑hole verification in component production, jig making and fitting operations.

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.
