Spi CMS160712101 Groove Micrometer 1-2 Inch Mechanical

Product Description

The SPI CMS160712101 is a mechanical groove micrometer designed to measure both inside and outside groove dimensions with high precision. It covers an inside measurement range of 1.05 to 2.05 inches and an outside measurement range of 1 to 2 inches, with a graduation and accuracy of 0.001 inches. The measuring disc diameter is 13 mm, and the non-rotating spindle and carbide anvil and spindle materials help maintain consistent contact and reduce wear during repeated use. This instrument is calibrated and ships with a Short Form Certificate of Calibration traceable to NIST standards. It is intended for use by machinists, quality control technicians, and precision measurement professionals in industrial and manufacturing environments.

This groove micrometer is suited for measuring internal and external grooves, recesses, and undercuts where standard micrometers cannot reach. The 3.38-inch reach length allows access to narrow or deep groove features. The chrome finish provides corrosion resistance in typical shop environments. It is packaged individually and comes with a carrying case for storage and transport. This tool is appropriate for production floor inspection, tool room measurement, and quality assurance applications in manufacturing, aerospace, automotive, and general machining operations.

Key Features

Compatibility

Designed for general-purpose groove measurement applications in machining and manufacturing settings where inside and outside groove dimensions fall within the 1 to 2 inch range.

Installation Notes

This instrument requires no installation. Prior to use, verify calibration using a known standard and inspect contact surfaces for wear or damage. Store in the included case when not in use to protect the measuring faces and maintain calibration integrity. Cleaning contact surfaces before each measurement is recommended to ensure accurate readings.
