Digital three‑point inside micrometer 50–63 mm — IP65, carbide measuring faces (Metav IndustryLine)

A precision digital three‑point inside micrometer intended for reliable internal diameter measurement, especially suited to blind‑hole and bore checks in workshop and production environments

• Digital three‑point inside micrometer 50–63 mm
• IP65 protection for dust and coolant resistance
• Carbide measuring faces for wear resistance
• Includes setting ring and extension for blind bores

Accurate three‑point measurement for blind bores

The three‑point measuring principle delivers a stable, self‑centering contact on the bore circumference, which reduces tilting errors and yields consistently repeatable diameters. With a measuring range of 50–63 mm and 0.005 mm stated accuracy, this instrument bridges the gap between bench micrometres and handheld gauges for internal checks. The unit is equipped with carbide measuring faces, providing superior wear resistance where repeated contact with workpieces would otherwise change results over time. The robust three‑leg contact is therefore beneficial for routine quality control and first‑off inspections.

Robust design and IP65 protection for shopfloor use

Constructed for active manufacturing environments, the micrometer carries an IP65 ingress rating that protects the electronics against dust and low‑pressure water jets. The sealed electronics combined with a solid frame and carbide anvils make the instrument tolerant of coolant splash and routine handling. The delivered case ensures secure transport and storage, and the included setting ring (62 mm) supports quick verification against a master standard. Together these features reduce downtime from instrument damage and increase confidence when measurements are performed directly at the machine or in the inspection bay.

Digital functions and workflow integration

The digital readout offers ON/PRESET, mm/inch conversion and HOLD functionality for straightforward operation in mixed‑unit environments. Resolution is 0.001 mm, visible on the display for fine adjustments; the micrometer also provides RB 6 data output for straightforward integration into SPC systems or data loggers, simplifying transfer into production control software. Supplied extensions enable measurement of blind holes and recessed features; the compact instrument format combined with connectivity options accelerates data acquisition and reduces transcription errors in recurring production checks.

Application focus and practical benefits

Designed for standard‑range internal measurement tasks, this micrometer is classified in the standard measuring category (best balance of reach and rigidity for 50–63 mm). It is particularly effective for bore inspection, spindle checks and fixture verification where quick, repeatable readings and wear‑resistant contacts are required. The delivered kit—setting ring and extension—removes the need for immediate additional purchases and supports calibration against a traceable standard during initial setup. For workshops seeking a dependable, shop‑ready internal gauge, the combination of three‑point contact, digital readout and sealed protection represents a pragmatic choice.

FAQ

What makes a three‑point inside micrometer better for blind bores?
The three‑point contact automatically centres on the bore and reduces tilting errors, which is why the Digital three‑point inside micrometer 50–63 mm from Metav IndustryLine is recommended for blind‑hole checks.

Can the micrometer be used in a wet or dusty workshop environment?
Yes, the instrument is rated IP65, offering protection against dust ingress and low‑pressure water jets, so it is suitable for use on the shopfloor under typical coolant and dust exposure.

Is data output available for statistical process control?
The micrometer provides RB 6 data output, allowing measurement values to be transmitted to SPC systems or data loggers for process monitoring.

Are measuring faces replaceable and wear‑resistant?
The measuring faces are made of carbide, which is wear‑resistant; worn anvils can be serviced or replaced by qualified maintenance to retain accuracy.

Does the delivery include calibration or a setting standard?
The delivery includes a setting ring (62 mm) and an extension; these accessories allow verification against a master standard during setup and periodic checks.
