12-16mm Three-Point Internal Micrometer With Adjustment Ring And Extension, 0.005mm Accuracy - Metav IndustryLine

The combination of three-point measurement, 0.005 mm accuracy and a compact 12–16 mm range ensures stable, repeatable internal readings for blind bores; the instrument is supplied with a setting ring, an extension and a transport case. Order the three-point internal micrometer directly via Metav Werkzeuge or ask our consultants if needed.

Three-point internal micrometer — Metav IndustryLine (12–16 mm, 0.005 mm)

The Three-point internal micrometer is a precision instrument for centred internal diameter measurement of blind bores in fine mechanical and general metalworking applications.

• Three-point contact for centred readings
• Range 12–16 mm for micro measurements
• Accuracy 0.005 mm for fine inspection

Stable centring for repeatable internal measurements

A three-point measuring system guarantees automatic centring inside a bore, reducing alignment error and speeding up inspection loops. The triple-contact geometry stabilises the measurement axis, which together with the instrument’s 0.005 mm accuracy yields highly repeatable results even on short, deep blind holes. For production and quality-control environments this translates into fewer re-measures and more reliable pass/fail decisions, supporting efficient workflow and predictable throughput.

Compact design tuned to micro-range applications

Classified within the micro segment (12–16 mm), this model is tailored to fine-mechanical tasks where small size and rigidity matter. Short measuring members remain torsion-resistant and are therefore well suited to watchmaking, precision assemblies and toolroom checks. The instrument includes a matt chrome-plated scale and vernier for durable, low‑glare reading, plus practical accessories — a setting ring (size 12), a dedicated extension (100×Ø11.7) and a transport case — enabling immediate use at the bench or on the shop floor.

Workshop-proven build for dependable inspection results

The analogue vernier mechanism provides tactile, direct operation without electronics, offering a robust solution for routine inspection. The presence of defined measuring faces and a concise length of 75 mm keeps handling straightforward while the overall mass (0.8 kg) gives a reassuring feel during measurement. Designed for blind-bore measurement, the instrument reduces common measurement variability and integrates easily into existing inspection routines, making it a pragmatic choice where precise internal diameters must be documented reliably.
