0.65-0.8″/16-20mm Digital Three-Point Internal Micrometer

The Three-Point Digital Internal Micrometer is designed for accurate and repeatable measurement of internal diameters in machining, manufacturing, and inspection applications. Its self-centering three-point measuring system ensures reliable bore measurements with minimal operator influence.

The large digital display provides inch and metric readings with a resolution of 0.00004″ (0.001 mm) and an accuracy of ±0.00016″ (±0.004 mm). Precision-ground carbide measuring contacts deliver excellent wear resistance and long-term accuracy, while the ratchet stop applies consistent measuring force for dependable results.

Ideal for measuring blind and through bores, this micrometer is supplied in a durable protective storage case and is well suited for CNC machine shops, tool rooms, quality control, and production environments.
