Three-point internal micrometer M312.433 — 12–16 mm, 0.001 mm resolution (Metav IndustryLine)

A three-point internal micrometer M312.433 engineered for precise measurement of blind holes and small internal diameters in fine mechanical and workshop environments

• Three-point design for stable internal contact
• 0.001 mm resolution for sub-micron checks
• Includes setting ring and extension
• Supplied in a protective transport case

Accurate internal measurement for fine bores

The three‑point design delivers repeatable contact around the bore circumference, which stabilises readings in small diameters. With a resolution of 0.001 mm and an assessed accuracy of ±0.005 mm, the instrument is suited to demanding inspection tasks where small deviations matter. Classified in the micro range (12–16 mm), this gauge bridges the gap between bench micrometres and larger internal measurement systems, making it especially useful for precision components, toolmaking and watch‑ and micro‑part measurement where controlled contact and fine resolution are decisive.

Built for workshop durability and convenient calibration

Key mechanical elements are finished for longevity: the matt chrome‑plated scale and vernier resist wear while remaining easy to read, and the device features hardened measuring faces to preserve accuracy under frequent use. A dedicated setting ring (16 mm) is supplied to verify and adjust the instrument quickly, while the included extension (152.4 x Ø11.8 mm) expands reach for deeper blind‑hole checks. Delivery in a protective transport case keeps all components secure and ready for immediate use on the shop floor or in the inspection room.

Practical handling and application benefits

Ergonomic balance and clear graduation support single‑operator measurement workflows: the three‑point mechanism minimises tilt sensitivity and the construction yields consistent results in blind‑hole scenarios. Weighing approximately 0.8 kg, the assembly is stable in hand without being cumbersome, so repetitive inspection cycles remain efficient. Supplied components and the protective case reduce setup time and storage concerns, enabling rapid integration into quality control routines for small bores and internal diameters.
