Spi CMS160712056 Electronic Bore Gage 1-1.2 in

Product Description

The SPI CMS160712056 is an electronic bore gage designed for precise internal diameter measurement in machining, engine rebuilding, and quality-control applications. It covers a measuring range of 1 to 1.2 inches with a resolution of 0.0001 inches and accuracy up to 0.00016 inches. The gage uses a 3-point solid carbide head for consistent, repeatable contact and features a pistol-grip handle for single-handed operation. A built-in indicator is included, and the unit ships with a CR2032 battery and a fitted carrying case. This tool is used by machinists, toolroom technicians, and precision measurement professionals who require reliable bore inspection without setup delays.

The CMS160712056 is suited for residential and commercial machine shop environments, engine rebuilding facilities, and manufacturing quality-control stations. Its 3.64-inch gage depth allows measurement access into most standard bores within its range. The pistol-grip design supports right- and left-hand viewing, making it practical across different operator preferences and workstation orientations. Automatic shut-off helps preserve battery life during extended use cycles.

Compatibility

Designed as a precision bore measurement tool for use with bores ranging from 1 to 1.2 inches in diameter; compatible with standard machining and engine-rebuilding inspection workflows where 3-point bore gage measurement is specified.

Installation Notes

This gage is handled and calibrated by machinists or metrology technicians; no power lockout is required, but the workpiece should be secured and at thermal equilibrium before measurement to avoid dimensional errors from heat expansion. Do not force the gage head into the bore — insert with light hand pressure and allow the 3-point head to self-center. Follow the manufacturer's calibration procedure using a reference ring gage before taking production measurements.
