Spi CMS160712065 Electronic Bore Gage 0.275-0.35 in

Product Description

The SPI CMS160712065 is an electronic bore gage designed for precise internal diameter measurement in tight bore ranges. It covers a measuring range of 0.275 to 0.35 inches with a resolution of 0.0001 inches and accuracy up to 0.00016 inches. The gage uses a 3-point solid carbide contact head, which self-centers in the bore for consistent, repeatable readings. A pistol grip handle allows single-handed operation, and the display supports both right and left hand viewing. An automatic shut-off feature conserves battery life. The unit ships ready to use with a CR2032 battery installed and comes furnished in a fitted protective case.

This bore gage is suited for machinists, tool-and-die technicians, and quality control inspectors working with small-diameter bores in precision manufacturing, engine rebuilding, hydraulic component service, and similar trades. The 2-inch gage depth allows access to typical bore depths encountered in production and maintenance environments. Its compact, ergonomic form is appropriate for both shop-floor use and bench inspection work where consistent bore measurement is critical to fit and function.

Installation Notes

Calibrate the gage to a master ring or setting fixture at the nominal bore size before taking measurements. Power down the unit when not in use to preserve battery life. Handle the carbide contact heads with care to avoid impact damage, which can affect calibration and accuracy. Installation of a fresh CR2032 battery should be performed according to the battery compartment access procedure in the product manual.
