18-50mm Internal Precision Bore Gauge Carbide Measuring Faces 130mm Depth 0.01mm Resolution - Microtech Metrology

Robust analogue performance meets workshop practicality: the internal micrometer combines carbide measuring faces with a 130 mm reach to inspect bores from 18–50 mm reliably. Paired with a fine 0.01 mm dial reading and an accuracy of ±0.012 mm, this gauge supports consistent in-process checks — order via Metav Werkzeuge or consult our specialists for application advice.

Internal Micrometer (Analogue Bore Gauge) by Microtech Metrology — Carbide Faces, 18–50 mm

The internal micrometer is an analogue bore gauge for precise internal diameter inspection in workshops and quality control environments.

• Analogue dial with 0.01 mm resolution
• Measuring range 18–50 mm
• Carbide measuring faces for wear resistance
• 130 mm measuring depth for deep bores

Reliable readings for everyday inspection

The instrument delivers dependable numerical discrimination thanks to its 0.01 mm dial graduation and an overall accuracy of ±0.012 mm, making it suitable for routine quality checks and workshop inspections. The analogue display provides an immediate visual result that is easy to interpret on the shop floor, reducing measurement time compared with more elaborate setups. As an entry-level fine measuring device with mechanical indication, the gauge supports swift go/no-go decisions while maintaining traceable measurement quality.

Wear-resistant contact for sustained performance

Equipped with carbide measuring faces, the gauge is designed to withstand repeated contact with metal surfaces without rapid wear. This hard material ensures that nominal geometry of the contact points remains stable over prolonged use, minimising drift in results and preserving repeatability across long production runs. The robust contact surfaces make the instrument especially appropriate where frequent checks of small-diameter bores are required and where replacement of softer contacts would otherwise increase downtime.

Reach and handling for confined bores

A 130 mm measuring depth provides access to deeper bores and recessed features that are common in assemblies and fixtures, while the 18–50 mm measuring range covers many common internal diameter checks found in precision components. The gauge’s slender profile and mechanical construction facilitate use in restricted spaces where larger instruments cannot reach, allowing technicians to measure internal diameters without dismantling assemblies or using complex adaptors.

Shop-friendly operation and maintenance

Designed for straightforward handling, the analogue mechanism requires minimal setup and is easy to maintain in a production environment. With a mechanical indicator that reads in fine steps, the device reduces reliance on batteries and electronics, offering continuity in rougher conditions. Routine checks of contact cleanliness and correct seating of the measuring faces are sufficient to keep the gauge within expected performance. For organisations seeking consistent in-process control with low operational overhead, this fine measuring instrument balances ease of use with professional-grade durability.
