Spi CMS160712151 Dial Bore Gage 0.4-0.7 in 9 Anvil

Product Description

The SPI CMS160712151 is a dial bore gage designed for precision internal diameter measurement in machine shop, maintenance, and quality-control environments. It covers a measuring range of 0.4 to 0.7 inches in diameter with a probe depth of 4 inches, making it suitable for bores, cylinders, and holes that require close-tolerance inspection. Accuracy is rated at 0.0003 inches. The gage ships with a white-face AGD Group 2 dial indicator already mounted, along with 9 anvils, sub-anvils, spacers, and a short-form certificate of calibration. It is stored and protected in a fitted carrying case.

This gage is used by machinists, tool-and-die technicians, maintenance mechanics, and quality-control inspectors who need repeatable internal bore measurements. It is suited for verifying cylinder bores, valve guides, bushings, and similar close-tolerance cylindrical features in both production and repair settings. The 4-inch probe depth allows access to deeper bores without requiring an extension. The included calibration certificate supports documentation requirements in ISO and quality-system environments.

Compatibility

Designed as an OEM-style precision measurement tool compatible with standard AGD Group 2 dial indicator accessories and bore gage interchangeable anvil sets within the 0.4 to 0.7 inch measurement range.

Installation Notes

Dial bore gages are set and used by machinists or quality-control technicians; no power source is required. Before use, zero the gage against a calibrated ring gage or outside micrometer set to the nominal bore size. Handle the contact anvils carefully during installation to avoid altering the set dimension. Store in the fitted case when not in use to protect the dial indicator and anvil tips from damage.
