Bügelmicrometer M307.025 — Groove micrometer, 100–125 mm range, 0.01 mm reading (Metav IndustryLine)

The Bügelmicrometer M307.025 is an analogue frame instrument designed for precise measurement of grooves and slots in workshop and production settings, offering a balance of reach and rigidity suitable for standard machine‑shop tasks.

• Groove measurement 100–125 mm
• 0.01 mm scale reading
• Repeatability ±0.008 mm
• Ratchet stop and fixed spindle

Reliable standard-range measurement for everyday workshop use

This groove micrometer is built for the standard range (100–300 mm) of workshop inspection, here delivered as a 100–125 mm instrument that balances reach with structural stiffness. That compromise reduces deflection compared with longer instruments while still covering common slot and groove sizes encountered in jig, fixture and component work. The analogue format avoids electronic dependencies, providing a simple, robust tool that integrates directly into established inspection routines and bench setups.

Precision mechanics that reduce measurement scatter

Fine threads and a defined spindle pitch of 0.5 mm convert hand movement into accurate axial travel; the instrument reads to 0.01 mm while achieving an operational repeatability around ±0.008 mm. The integrated ratchet stop enforces a consistent measuring force and the non‑rotating spindle limits wear on the anvil surfaces, both features helping to keep measurement scatter low and inspection results comparable between operators. For quality control, this mechanical consistency translates into fewer false rejects and steadier process decisions.

Slim measuring faces and a frame suited to grooves

The micrometer’s measuring faces are formed for slot work, with contact surfaces approximately 0.75 x 6.5 mm, allowing access into narrower grooves without undue contact stress. The robust frame and precise spindle guidance maintain alignment during use, while the non‑digital design ensures immediate availability for repeated checks without battery changeovers or electronic drift. The instrument’s straightforward construction also simplifies routine checks and maintenance.

Practical applications and productivity gains

Intended for toolrooms, production inspection and fixture verification, the instrument is particularly useful for slot depths, keyways and groove widths where a frame micrometer gives a direct contact reading. The combination of a clear 0.01 mm scale and mechanical force control supports faster throughput on inspection benches and reduces rework by catching deviations early. As part of a disciplined inspection workflow, the device contributes to measurable savings through lower scrap rates and fewer machine downtime events.
