T‑slot internal micrometer M311.011 — 0–25 mm range, 0.01 mm reading (Metav IndustryLine)

The T‑slot internal micrometer M311.011 is a compact analogue micrometer designed for precise measurement of internal cross‑slots and grooves in fine mechanical parts and fixtures

• Double scale for internal and external measurement
• Measuring range 0–25 mm for fine tasks
• Readability 0.01 mm for precise reading
• Supplied in protective transport case

Precision that serves fine mechanical requirements

The instrument delivers a 0.01 mm reading and a stated accuracy of 0.01 mm, making it suitable where small tolerances matter. The analogue vernier mechanism combined with a 0.5 mm spindle pitch provides a tactile, backlash‑resistant feel while turning, which benefits inspection tasks that rely on repeatable hand‑held measurement. The measuring mandrel of Ø 6.5 mm and the compact design reduce probing interference in narrow grooves, so set‑ups remain efficient without sacrificing clarity. This level of specification supports quality assurance steps in small‑batch production and toolroom inspection.

Compact build for workshop convenience and repeatability

At 178 mm overall length and weighing 0.2 kg, the gauge is easy to manoeuvre and store, yet sufficiently rigid for consistent readings in confined assemblies. The instrument covers external and internal measurement across 0–25 mm and 1.6–26.5 mm respectively, which places it in the micro range for precision metrology—ideal for watchmaking, small fixtures and precision mechanical components. The integrated double scale allows fast cross‑checking of inside and outside dimensions without swapping tools, reducing handling time and measurement uncertainty. The device is supplied in a protective transport case to safeguard the micrometer during storage and transport.

Practical use, maintenance and application scenarios

Intended for measuring internal T‑slots and cross‑grooves, the instrument suits inspection benches, jig and fixture checks, and sample testing in component assembly. The analogue reading is intuitive for experienced users and retains reliability where simple, robust measurement is preferred over networked data output. Routine maintenance is limited to keeping the spindle and anvils clean and lightly oiled; periodic professional calibration is recommended to maintain traceability. If a calibration certificate with a specific standard is required, Metav Werkzeuge can advise on available options and test house procedures.
