Spi CMS220623067 Three Point Bore Micrometer 2-2.5 in

Product Description

The SPI CMS220623067 is a three-point bore micrometer designed for precise internal diameter measurement in the 2 to 2.5 inch range. It delivers an accuracy of plus or minus 0.0002 inches and a resolution of 0.00005 inches, making it appropriate for high-tolerance bore inspection work. The measuring faces are carbide for durability and long service life. Built-in Bluetooth data transmission allows direct wireless output to compatible data collection systems, eliminating manual transcription. It carries an IP65 rating for protection against dust and low-pressure water contact. This tool is used by machinists, quality control technicians, and precision measurement professionals working in manufacturing and industrial environments.

The CMS220623067 is suited for internal bore measurement where standard two-point micrometers cannot reach or provide sufficient accuracy. The 330-degree rotating display allows easy reading during multi-angle measurements, including near the bottom of blind holes. The 5-inch throat depth extends reach into deeper bores. A tolerance preset and GO/NG judgment function supports fast pass/fail inspection workflows on production floors or in field service environments where consistent repeatability is critical.

Compatibility

Designed as a direct-use three-point bore micrometer for internal diameter measurement applications requiring Bluetooth data output and compliance with ASME B89.1.13 standards.

Installation Notes

This instrument is used by qualified metrology or quality assurance personnel; no permanent installation is required. Before use, verify calibration with the included setting ring and confirm the CR2450 lithium battery is installed and charged. Follow ASME B89.1.13 handling guidelines to avoid damage to the carbide measuring faces. Store in the provided case when not in use to protect the precision contact surfaces.
