With carbide measuring faces and a ratchet stop, the instrument resists wear and maintains consistent measuring pressure, making it ideal for engineers, machinists, quality‑control professionals, and hobbyists who demand reliable results.

Three‑point internal contact with carbide faces: Delivers stable, repeatable measurements with excellent wear resistance for long‑term accuracy.
Ratchet stop for consistent measuring pressure: Ensures uniform contact force, prevents over‑tightening, and improves repeatability across measurements.
Wide range up to 300 mm with setting ring and extension rods: Flexible coverage for various bore sizes, with ready‑to‑use accessories that speed setup and measurement.

Equipped with a 0.001 mm graduation, this bore micrometer enables fine tolerance control on internal diameters. The included setting ring and extension rods expand measurement versatility, helping you work faster, maintain quality, and keep production moving with confidence.
