M309.060 — Depth micrometer (0–100 mm) with ratchet stop and curved anvils

The M309.060 is a precision depth micrometer designed for workshop and inspection tasks, offering fine resolution and a practical accessory set for routine depth measurements up to 100 mm.

• 0–100 mm measuring range
• 0.01 mm reading resolution
• Ratchet stop for constant contact
• Curved measuring faces for reliable contact

Precision that reduces rework and speeds inspection

The instrument delivers high repeatability attributable to its fine mechanical design and ratchet stop, which stabilises the measuring force and reduces operator‑induced variation. With a reading resolution of 0.01 mm and a declared accuracy of ±0.005 mm, this analogue depth gauge fits routine quality control where tight tolerances are required. The design supports consistent results across repeated measurements, so batch inspection becomes more predictable and corrective cycles are reduced.

Practical features that make measurement faster

Built for workshop efficiency, the device includes a set of four interchangeable measuring rods and a quick‑change system for the measuring inserts, enabling fast adaptation to different depths without disrupting workflow. The curved measuring faces ensure secure contact on uneven surfaces and small bores, improving stability during depth readings. The mechanical construction is straightforward to service, minimising downtime and keeping throughput steady.

Ergonomics and handling that protect measurement integrity

A dedicated ratchet stop provides uniform tightening and prevents over‑loading of the spindle, while the compact bridge design suits bench and fixture work where manoeuvrability matters. The analogue scale is intuitive for users familiar with mechanical gauges and requires no batteries, which simplifies long‑term operational readiness. The combination of robust handling and accessible maintenance supports continuous use in production environments.

Suited classification and typical applications

This depth micrometer sits within the standard measuring‑range class for workshop metrology and is appropriate for component inspection, jig and fixture checks, and depth verification in machining operations. Its capability set addresses everyday needs in metalworking and general engineering, adding measurable control to assembly and inspection processes.
