Three‑point internal micrometer MS908.672 — 12–20 mm range, 0.005 mm vernier (Metav IndustryLine)
The Three‑point internal micrometer MS908.672 is an analogue, self‑centring gauge designed for accurate measurement of blind bores within the micro range, where compact size and repeatable centring are essential.
- Self‑centring three‑point measurement
- Carbide measuring faces for wear resistance
- Resolution 0..005 mm for fine readings
Precision where small tolerances matter
This instrument is tailored to the micro range (12–20 mm), a segment where stiffness and compactness determine repeatability. The three‑point geometry automatically centres in blind bores, reducing operator alignment error and speeding up routine checks. With an analogue vernier reading at 0.005 mm, the gauge enables fine discrimination that supports tight tolerances without the complexity of digital systems. The compact format is especially useful in repair benches, toolrooms and micro‑assembly stations where space and manoeuvrability are constraints.
Durable construction for frequent shop use
Key contact surfaces are fitted with carbide measuring faces, providing excellent resistance to wear and abrasion and maintaining measurement integrity over many cycles. The instrument’s analogue vernier construction offers a robust, low‑maintenance solution for production environments. An adjustment ring (16) allows controlled settling of the measuring head, while the solid mechanical design minimises play and drift during repeated inside measurements.
Practical set composition and extendibility
Supplied as a set of two, the micrometers offer complementary coverage for daily shop workflows and quick changeover between inspection tasks. Extensions of 150 mm are available for deeper blind bore access, enabling the same measuring principle to be applied where reach is required. The compact set format reduces tool change time and simplifies storage for inspection kits on the shop floor.
Application suitability and operator benefit
Designed specifically for blind‑hole measurement, the gauge removes the need for complex adapters in many common tasks. The self‑centring action reduces the influence of operator alignment, while the fine vernier graduation supports confident pass/fail assessments in first‑operation inspection and incoming goods control. The analogue nature makes it straightforward to interpret results and integrate the device into established quality routines without training overhead.

FAQ
What measuring range does the instrument cover?
The Three‑point internal micrometer MS908.672 covers a measuring range of 12.0–20.0 mm, placing it in the micro range suitable for fine mechanical work.
Is this gauge suitable for blind‑hole inspection?
Yes — the self‑centring three‑point design is specifically intended for blind‑hole (Sackloch) measurement and ensures reliable centring in such applications.
How fine is the reading and how is it read?
The analogue vernier provides a reading resolution of 0.005 mm; readings are taken from the vernier scale, offering precise manual measurement without electronics.
Are the measuring faces robust enough for regular use?
Measuring faces are made of carbide, giving the MS908.672 high wear resistance and long service life even under frequent shop use.
Does the delivery include extensions and how many pieces are supplied?
The delivered set comprises two instruments and includes extensions of 150 mm to extend reach into deeper blind bores.
