Micrometer M309.254 — Disc‑anvil micrometer, 100–125 mm, Ø30 mm (Metav IndustryLine)

The Micrometer M309.254 is a disc‑anvil micrometer designed for precise external measurements in machining and inspection tasks, offering a robust frame finish and a matt‑chrome measuring drum for reduced glare and lasting legibility.

• Measuring range 100–125 mm
• Accuracy 0.006 mm for fine readings
• Ø30 mm disc anvil with matt chrome drum
• Supplied with protective transport case

Consistent accuracy for everyday workshop control

The instrument delivers a 100–125 mm measuring range that places it in the standard class for workshop and metalworking use, balancing reach and rigidity for general production tasks. With a stated accuracy of 0.006 mm, the micrometer supports routine quality control where tight tolerances matter. The analog scale provides an able reading step of 0.01 mm, while the precision construction reduces measurement scatter; this combination enables dependable comparative checks and helps maintain process stability on the shop floor.

Design choices that reduce operator influence

Built with a non‑rotating measuring spindle and ratchet stop, the device enforces a repeatable measuring force so readings are less affected by operator variation. The Ø30 mm disc anvil spreads contact pressure and is paired with a matt‑chrome measuring drum to limit reflection during reading. The lacquered frame improves corrosion resistance and surface durability, supporting long service life in daily use. These features together enhance repeatability and reduce rework in serial production.

Handling, storage and transport made practical

Weighing approximately 1.2 kg, the micrometer remains manoeuvrable while feeling substantial enough for stable measurements. The unit is supplied in a protective transport case, easing safe storage and on‑site movement between workstations. The ratchet mechanism prevents over‑tightening, protecting specimens and the instrument itself. For workshops seeking tools that combine user‑friendly handling with rugged‑service design, this micrometer meets those needs without complex maintenance.

Applications and benefits for production and inspection

Ideal for component inspection, set‑up checks and general metalworking measurements, the micrometer is suited to repetitive external gauging of shafts, rings and turned parts. The robust finishing and reliable measuring drum allow quick readings under typical workshop lighting, while the construction supports routine use in jigs, fixtures and incoming inspection. Selection of this instrument contributes to shorter inspection cycles and a more consistent quality output across manufacturing steps.
