Spi CMS220623063 Three Point Bore Micrometer 1.2-1.6 in

Product Description

The SPI CMS220623063 is a three-point inside bore micrometer designed for precision internal diameter measurement in the 1.2 to 1.6 inch range. It delivers an accuracy of plus or minus 0.0002 inches and a resolution of 0.00005 inches, making it suitable for tight-tolerance bore inspection work. Built-in wireless Bluetooth data transmission allows measurements to be sent directly to a connected device without manual transcription. The measuring faces are carbide-tipped for wear resistance and long service life. A 330-degree rotating display lets technicians read measurement data at multiple angles, including near the bottom of blind holes.

This micrometer is used in precision machining, metrology labs, and quality control environments where accurate bore measurement is critical. The rotating spindle and positive lock nut allow repeatable, stable readings in production and inspection settings. The GO or NG judgment function and tolerance preset capability support pass or fail inspection workflows. A throat depth of approximately 4.13 inches allows reach into deeper bores. The instrument is calibrated to ASME B89.1.13 standards and includes a traceability certification, making it suitable for documented inspection processes in both shop floor and controlled metrology environments.
