Spi CMS160726115 Inside Micrometer Set Chrome

Product Description

The SPI CMS160726115 is a mechanical inside micrometer set designed for accurate internal bore and diameter measurements in precision machining, maintenance, and quality control applications. The set includes one extension rod and measures from a minimum of 0.5000 inches, with a maximum extension rod length of 6.0000 inches. Accuracy is rated at 0.000160 inches (0.003 mm), and the ratchet stop thimble ensures consistent measuring force with every reading. Carbide measuring surfaces resist wear during repeated use. The chrome finish provides corrosion resistance for shop environments. Two pieces are included in a fitted case.

This inside micrometer set is suited for machinists, tool and die makers, maintenance technicians, and quality control inspectors working in manufacturing, fabrication, or precision repair environments. It is appropriate for measuring bores, housings, and internal features where tight tolerances are required. The self-centering contact points simplify alignment during measurement, making it practical for both production floor and bench use. The fitted case keeps the instrument and accessories organized between uses.

Compatibility

Designed as an OEM-style mechanical inside micrometer set suitable for general precision measurement tasks requiring internal bore gauging within the specified range.

Installation Notes

This instrument should be handled and stored by a qualified technician or machinist familiar with precision measuring tools. Before use, verify calibration with the included setting ring and inspect carbide contact surfaces for wear or damage. Keep the fitted case closed when the tool is not in use to protect the instrument from contamination and impact. Do not use the tool to measure surfaces with burrs or sharp edges that could damage the carbide tips.
