Three-point internal micrometer M312.432 — 10–12 mm range, 0.001 mm resolution (Metav IndustryLine)

The three-point internal micrometer M312.432 is a compact precision gauge designed for accurate measurement of blind-hole diameters in the 10–12 mm band, combining a three-point contact system with fine 0.001 mm increments for repeatable results.

• Three-point system for blind-hole diameters
• Measurement range 10–12 mm with 0.001 mm resolution
• Includes setting ring and 101.6×Ø5.8 mm extension
• Matt chrome scale and vernier for durable reading

Precision tailored for blind-hole inspection

The instrument uses a three-point measuring system that centres reliably in blind bores, converting contact geometry into stable diameter readings. With a 0.001 mm reading step and a stated measurement uncertainty of ±0.004 mm, the gauge is suited to fine internal-diameter verification where repeatability and clear numerical resolution matter. The three-contact design reduces eccentricity errors compared with two-point probes and simplifies interpretation of results in small diameters.

Practical handling that speeds up inspection routines

A compact build and a mass of approximately 0.6 kg make the gauge convenient at the workbench while providing adequate stiffness for consistent measurements. The supplied setting ring (10 mm) allows quick functional checks and adjustments before a batch run, while the 101.6 × Ø5.8 mm extension extends reach into deeper blind holes without compromising stability. The matt chrome scale and vernier resist glare in bright workshop lighting and preserve legibility over repeated use, reducing the need for frequent re-reading.

Designed for production and quality control environments

The construction and feature set make this instrument suitable for machine shops and inspection stations where small-diameter bores must be checked rapidly. The robust contact geometry and clear graduations support throughput: fast verification with traceable readings helps keep production flowing while maintaining documented quality. The three-point gauge complements standard internal measuring setups and can be integrated into routine quality-control procedures with minimal training.

Confidence from an established precision partner

Delivered as a complete package with the setting ring and extension, the gauge supports immediate deployment in inspection workflows. Backed by Metav IndustryLine, operators benefit from a supplier position focused on practical precision: a broad product range, tried-and-tested components and a logistics base in Emmerich that acts as a quality filter for the European market. The result is an instrument that combines measurable technical performance with supplier reliability for everyday workshop use.
