Spi CMS160713020 Dial Bore Gage 0.4 to 0.7 in 9 Anvil

Product Description

The SPI CMS160713020 is a dial bore gage designed for internal diameter measurement across a range of 0.4 to 0.7 inches. It features a 4-inch probe depth and ships with 9 anvils, sub-anvils, spacers, and an AGD Group 2 dial indicator with a white dial face. Accuracy is rated at 0.0006 inches, making it suitable for close-tolerance inspection work. The included short-form certificate of calibration confirms the instrument ships traceable. It is housed in a fitted carrying case for field and shop use. Machinists, tool and die shops, maintenance technicians, and quality control personnel are the primary users of this instrument.

The CMS160713020 is suited for bore measurement in residential and commercial maintenance environments, machine shops, and manufacturing quality inspection stations. The 0.4 to 0.7 inch measurement range covers small-bore applications such as hydraulic cylinders, pump housings, valve bodies, and similar components. The 4-inch probe depth allows access into deeper bores without an extension. The 9-anvil configuration provides coverage across the full stated range without requiring a separate gage set.

Installation Notes

Dial bore gages are precision instruments and should be handled and stored in their fitted case when not in use. Zero the gage against a calibrated master ring or setting fixture before taking measurements. Do not force the anvils into a bore; apply only light, consistent contact pressure to avoid shifting the indicator needle and introducing measurement error. Calibration should be verified periodically per your shop quality plan or applicable inspection standards.
