Three-point internal micrometer MS908.668 — self-centring, analogue unit (225–240 mm)

A three-point internal micrometer designed for precise inspection of blind bores and similar internal features in machine and toolmaking environments.

• Self-centring three-point measurement
• Measuring range 225–240 mm
• Interchangeable measuring insert
• Hard-metal measuring faces

Consistent accuracy that speeds up decision-making on the shop floor

The instrument provides a measuring range of 225–240 mm and an accuracy of ±0.007 mm, combined with a reading of 0.005 mm on the analogue scale. This balance of resolution and repeatability makes it well suited for standard workshop quality control where swift go/no-go decisions are required. The numeric stability of the mechanism reduces the need for repeated measures, shortening inspection cycles while maintaining documented tolerances. As a standard measuring class tool, it fits seamlessly into routine measurement plans for machining, assembly and maintenance tasks.

Robust three-point mechanism for reliable blind-hole measurement

A self-centring three-point system ensures the measuring heads align concentrically in blind bores, converting variable contact positions into a single, reproducible diameter value. The interchangeable measuring insert extends the instrument’s service life and enables adaptation to particular bore geometries without replacing the entire tool. Hard-metal measuring faces resist wear during repeated contact in production environments, reducing maintenance intervals and protecting measurement integrity. These features together deliver dependable internal measurements with minimal operator adjustment.

Practical integration, traceability and workshop benefits

Designed as an analogue instrument that is easy to handle, the micrometer combines traditional tactile control with industrial resilience. Its compact overall profile (length approx. 145 mm) and clear scale make it straightforward to use at the bench or in a fixture. Classified within the standard (100–300 mm) range, the tool suits common machine‑ and metal‑working applications where reach, stiffness and one‑hand operation are priorities. The device is supplied by Metav IndustryLine as SKU MS908.668, allowing straightforward specification management in procurement and inspection records.
