Internal micrometer set by Microtech Metrology — 18–450 mm, carbide measuring faces

The internal micrometer set provides precise internal diameter measurement across a broad span for workshop and inspection use, combining a finely graduated mechanical dial with wear‑resistant carbide contact faces for repeatable results in jigs, housings and bearing bores.

• Internal micrometer set 18–450 mm measuring range
• Carbide measuring faces for long wear life
• 0.001 mm readout resolution on mechanical dial
• Medium class range for fixtures and housings

High precision where internal geometry matters

This set delivers ±0.008 mm accuracy and a 0.001 mm readout resolution on an analogue dial, offering the combination of tactile control and measurable repeatability expected in production control. The fine graduation on the dial and the mechanically stable spindle permit robust comparison measurements and traceable inspection steps; the design reduces operator-induced variation by favouring a steady measuring action, so recurring checks on internal diameters become faster and more reliable. The result is measurable process stability in assembly or incoming inspection tasks.

Versatile set format for workshop measurement tasks

Supplied as a set covering 18–450 mm, the kit falls into the Medium (300–500 mm) class of internal measuring instruments: it balances reach and stiffness for larger components such as housings, flanges and precision fixtures. The specified measuring depth 130–2000 mm allows access into deeper bores and stepped parts without improvised extensions. Delivered in matched increments, the set enables quick selection of the correct gauge for different bore sizes and reduces changeover time during serial checks.

Durable contact geometry and service-friendly handling

The instrument's carbide measuring faces resist wear and preserve measuring reliability over long service intervals, which reduces recalibration frequency and lowers lifetime cost of ownership. The analogue dial provides an immediate visual readout that is simple to interpret on the shop floor; the mechanical construction keeps maintenance straightforward and supports rapid field checks. For production environments prioritising uptime, the robust contact surfaces and solid construction contribute directly to fewer measurement-related stops.

How this improves process control

Incorporating a purpose-built internal measuring set into quality workflows shortens inspection cycles and improves first-pass yield by delivering consistent bore assessments at the point of manufacture. The clear dial reference and precise spindle travel help technicians detect small deviations early, enabling corrective actions before components proceed down the line. This contributes to operational efficiency and reduces rework costs in machining and assembly operations.
