Order the set directly via Metav Werkzeuge or contact our consultants for advice on matching extensions and gauges to specific bores. Three‑point internal micrometer MS908.673 — self‑centring, 0.005 mm analogue The Three‑point internal micrometer MS908.673 is an analogue, self‑centring inside micrometer designed for precise measurement of blind holes in fine mechanical and workshop applications Self‑centring three‑point measuring system Hardmetal measuring faces (carbide) Analogue resolution 0.005 mm Designed for blind‑hole measurement Repeatable centring for reliable results The micrometer’s defining benefit is its self‑centring three‑point head, which aligns reliably in blind bores and reduces off‑axis error during measurement. This design converts operator input into a consistent contact geometry, lowering variance between individual readings and helping to meet process tolerances with fewer rechecks. The analogue graduation with 0.005 mm division gives a clear, immediate view of dimensional changes; when traceable comparability is required, the instrument’s mechanical simplicity supports straightforward in‑house verification routines. Built for longevity and stable contact Measuring faces made from carbide (hardmetal) ensure high wear resistance where repeated contact with bore edges would otherwise round or score softer contacts. The harder contact points preserve nominal diameter and shape over long production runs, translating into lower replacement frequency and a steadier measuring baseline. Where repeatability over time matters for quality control, the combination of robust contact materials and the three‑point geometry yields consistent seating in the bore and predictable measurement behaviour. Practical set composition and extension options Supplied as a set of four, this analogue internal micrometer covers a practical range for precision blind‑hole work and fast gauge changes between nominal sizes. Extensions are available up to 150 mm, enabling larger or deeper bores to be reached without sacrificing centring performance. The instrument is analogue by construction, making it straightforward to use alongside existing mechanical measuring tools; shops that prefer simple, robust gauges will appreciate the minimal maintenance and easy field adjustments afforded by the setting rings. Clear advantages in process environments In repetitive inspection tasks or small‑batch production, the instrument’s self‑centring function reduces operator training time and speeds routine checks. The carbide faces and solid construction lower total cost of ownership by reducing wear‑related drift; together with the fine analogue graduation, these characteristics deliver a balance of durability and measurement fidelity that supports reliable quality control in component manufacture.

The instrument’s mass and geometry provide stable handling for workshop tasks, and the analogue mechanism is favoured where battery-free, low-maintenance tools are required. Prepared for medium-range workshop applications With a measuring span of 200–225 mm and a measuring depth of 140 mm, the instrument falls into the standard workshop range for medium-sized components, fixtures and assemblies. It is therefore well suited to machine shops, jig and fixture inspection, and quality checks on housings and sleeves where blind-hole diameters must be verified. The device is supplied without a setting ring; calibration and setting procedures should be planned accordingly. Traceable identification (GTIN and article number) is provided for inventory and procurement processes.

Technical data Article number: M312.150.S GTIN: 4054469158723 Category: Internal micrometers Facts Measuring range: 200–225 mm Measuring depth: 140 mm Accuracy: ±0.008 mm Reading: 0.005 mm Weight: 4.3 kg Tariff number: 90173000 Special features Three-point internal measuring geometry Carbide measuring faces Matt-chrome scale and vernier Ratchet thimble for reproducible force Analogue instrument for blind-hole bores Supplied without setting ring FAQ What measuring range does the instrument cover? The Three-point internal micrometer M312.150.S covers a measuring range of 200–225 mm and is intended for medium-sized workpieces. How precise is the measurement result? The device offers an accuracy of ±0.008 mm with a vernier reading increment of 0.005 mm, which supports routine dimensional checks and quality control. Are the contact faces suitable for high-use inspection? Yes; the contact faces are made from carbide, which increases wear resistance and prolongs service life even under frequent use. Is a setting ring included for calibration? Delivery is without a setting ring; calibration and setting must be performed with an appropriate gauge or reference ring. For which applications is this instrument especially suited? The instrument is optimised for blind-hole measurements in machine parts, assemblies and fixtures within the standard workshop range.

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.
