150–175mm Dial Micrometer With 30mm Anvil, Ratchet Stop, Painted Frame And Matt Chrome Thimble - Metav IndustryLine

Take advantage of a robust workshop micrometer that pairs a Ø30 mm disc anvil with a non-rotating spindle and ratchet stop for highly repeatable readings; order the instrument via Metav Werkzeuge or consult their specialists for application advice.

Disc-Anvil Micrometer ND 150–175 mm (Ø30 mm) — Metav IndustryLine

The Disc-Anvil Micrometer ND 150–175 mm (Ø30 mm) is a precision analogue micrometer for standard workshop measurement tasks, offering a stable contact geometry and features that support reproducible dimension checks.

• Ø30 mm disc anvil for stable contact
• Non-rotating spindle for repeatable readings
• Ratchet stop for consistent measuring force
• Supplied in transport case for safe handling

Accurate, repeatable measurements that speed up inspection

The instrument delivers a clear 0.01 mm reading combined with a stated accuracy of 0.007 mm, providing a reliable balance between resolution and robustness for everyday quality control. The non-rotating spindle reduces measurement artefacts caused by spindle rotation, while the ratchet stop enforces a consistent measuring force — both features that lower scatter between successive measurements and reduce the need for repeated checks. Designed for standard workshop spans, the 150–175 mm range covers medium-sized components commonly encountered in machining and assembly; this makes the tool an efficient choice for production inspection where speed and reproducibility matter.

Solid construction for repeatable handling and long service life

Built with a lacquered frame and a matt chrome-plated measuring drum, the micrometer combines corrosion-resistant finishes with a tactile, durable control surface. The Ø30 mm disc anvil provides a broad support area that stabilises contact on uneven or larger profiles, translating into fewer local deformations and more trustworthy measurements. At around 1.9 kg, the instrument conveys a reassuring mass that aids steadiness during use without compromising manoeuvrability for typical workshop handling. Supplied in a protective case, the unit is ready for transport between workstations and secure storage during shift changes.

Workflow benefits and practical integration into quality processes

As an analogue instrument with straightforward mechanical operation, the micrometer offers low-maintenance reliability and immediate readiness for shop-floor use. Marked by its SKU and traceable identifiers, the tool supports clear inventory and inspection records; the robust measuring geometry and ergonomic ratchet reduce operator influence, which helps maintain consistent parts acceptance criteria and shortens inspection cycles. For teams seeking pragmatic improvements in first-pass yield and fewer reworks, this model represents a cost-effective instrument that slots into existing quality-control routines with minimal setup.

FAQ

What is the measuring range of this micrometer?
The measuring range is 150–175 mm for the Metav IndustryLine disc-anvil micrometer M309.256, covering typical medium-sized workshop components.

How precise is the instrument in everyday use?
Resolution is 0.01 mm with an accuracy specification of 0.007 mm, which supports reliable production checks and routine quality control.

Why is a non-rotating spindle beneficial?
A non-rotating spindle reduces measurement errors introduced by spindle rotation; in the M309.256 this improves repeatability across repeated measurements.

Does the micrometer come with a protective case?
Yes, the micrometer is supplied in a transport case to protect the instrument during handling and transit.

What role does the ratchet stop play?
The ratchet stop enforces a consistent measuring force on each reading, helping to reduce operator-induced variation and improve reproducibility.
