Digital three-point internal micrometer set M312.276.PN – 20–50 mm, IP65, carbide measuring faces (Metav IndustryLine)

A Digital three-point internal micrometer set M312.276.PN designed for precise internal and blind‑hole measurement tasks in fine mechanical and workshop environments.

• IP65 protection for workshop environments
• Carbide measuring faces for long wear
• Digital display with mm/inch and HOLD
• Supplied in a transport case with accessories

Compact precision for micro-range inspection

The set is optimised for the micro measuring range (20–50 mm), where short measuring arms reduce bending and improve repeatability for small parts. The three‑point measuring geometry stabilises contact with cylindrical bores, producing consistent readings even in narrow blind holes; this makes the set suitable for precision checks on plugs, bearings and micromechanical housings. Conformity to DIN 863 underlines the mechanical design quality and ensures compatibility with standard workshop procedures.

Robust design for regular workshop use

Engineered for demanding shop floors, the instruments combine carbide measuring faces with an IP65 enclosure class for the electronic modules. The carbide tips resist wear during repeated bore checks, extending service life and maintaining measurement integrity. The sealed electronics reduce the risk of dust and coolant ingress during routine inspection, which supports dependable operation in production or maintenance environments and reduces downtime caused by instrument faults.

Efficient digital functions for traceable results

The integrated digital display features ON/PRESET, mm/inch conversion and a HOLD button for stable readings, while the built‑in data output RB 6 enables connection to data collection systems for quality documentation or SPC workflows. The 0.001 mm readout provides fine resolution appropriate for detailed internal measurements, and the digital interface streamlines transfer of values into inspection reports, increasing throughput in repetitive measurement tasks.

Ready-to-use set with accessories for blind‑hole measurement

Delivered as a four‑piece set with a setting ring and extension (150 × Ø15.8), the kit is furnished in a protective transport case for secure storage and movement between workstations. The configuration supports blind‑hole measurement applications thanks to the three‑point contact design and the included extension, permitting reliable access to deeper bores. The set balances accuracy and practicality for inspection benches and mobile metrology tasks.

FAQ

How is the set best applied for blind‑hole measurements?
The Digital three‑point internal micrometer set M312.276.PN (Metav IndustryLine) uses a three‑point contact design and supplied extension to centre reliably in blind holes, producing reproducible bore diameters even where radial access is limited.

What does IP65 protection mean for workshop use?
IP65 indicates that the electronic components are dust‑tight and protected against low‑pressure water jets, so the M312.276.PN set is suitable for typical shop‑floor conditions with coolant mist or airborne particles.

Can measurement data be exported to quality systems?
Yes — the set provides an RB 6 data output for direct connection to data collection devices or SPC systems, enabling the transfer of readings from the Metav IndustryLine instrument into inspection software.

Are the measuring faces durable for frequent use?
The carbide (hard‑metal) measuring faces fitted to the set are specified for wear resistance, extending lifetime under repeated bore inspection compared with softer contact materials.

Which application category does this set fall into based on range?
With a measuring range of 20–50 mm the kit is classified in the micro range, making it particularly suited to fine mechanical parts, watchmaking elements and small precision components.
