Three‑point internal micrometer set M312.274.M — digital, IP65 (Metav IndustryLine)

The Three‑point internal micrometer set M312.274.M is a compact, workshop‑grade instrument for precision measurement of blind bores and internal diameters in small components, supplied as a three‑piece set with setting ring and extension

• Three‑point measuring for stable bore contact
• Digital display with ABS/INC/UNIT functions
• IP65 protection against dust and splash

Precision designed for small bores and repeatable results

The set is engineered for consistent internal measurement in the micro range, covering a measuring span of 6–12 mm, which places it in the compact category ideal for fine mechanical work. The triple‑contact measuring principle gives a self‑centring action that reduces user‑dependent error and improves repeatability when checking blind holes. A finely graduated measuring drum with visible scale complements the digital display, enabling fast visual checks and cross‑verification. Compliance with DIN 863 confirms workshop suitability and predictable performance in serial inspection.

Robust measurement chain and clear data handling

Durability and usability are emphasised by the IP65 rating and matt‑chrome plated scale and vernier, which resist workshop contaminants while keeping legibility high. The electronic readout features ON/OFF/SET and ABS/INC/UNIT controls for flexible zeroing and unit selection, while the built‑in data output (RB 4.1) facilitates integration into inspection logs or SPC systems. Supplied accessories — a setting ring (6+8+10) and an extension (100×Ø5.7) — allow immediate calibration and reach adaptation, reducing setup time and keeping throughput steady.

Designed for everyday workshop use and tight tolerances

Supplied as a coordinated three‑piece set, this instrument reduces time spent changing tools and ensures matched performance across measuring ranges. The high display resolution (0.001 mm) supports fine inspection tasks where small deviations matter, while the three‑point contact lessens tilting and misalignment in short bores. Weight and handling characteristics have been balanced for single‑operator use in bench or machine‑side inspection. The combination of mechanical scale and digital readout gives a pragmatic dual‑verification approach that suits both production checks and documented quality control.
