Spi CMS160712153 Dial Bore Gage 1.4 to 2.4 in

Product Description

The SPI CMS160712153 is a dial bore gage designed for measuring internal diameters with high repeatability. It covers a measurement range of 1.4 to 2.4 inches in diameter with a probe depth of 6 inches, making it suitable for evaluating bores, cylinders, and housings where depth access is required. Accuracy is rated at 0.0003 inches, which supports close-tolerance inspection work. The unit includes an AGD Group 2 dial indicator with a white dial face for easy readability. Machinists, quality control technicians, and precision measurement professionals are the primary users of this instrument.

This dial bore gage is used in machine shops, manufacturing facilities, and maintenance environments where bore diameter verification is part of standard inspection procedures. The 6-inch probe depth allows measurement in relatively deep bores without requiring a separate extension setup. It is appropriate for both incoming inspection and in-process measurement of precision components such as pump housings, engine cylinders, and bearing bores.

Installation Notes

This instrument is handled and operated by machinists or quality technicians and does not require electrical installation. Before use, zero the gage against a calibrated ring gage or setting master at the target nominal diameter. Keep the instrument clean and store it in the fitted case when not in use to protect the dial indicator and contact points from damage.
