Spi 13-979-0 Dial Test Indicator Kit 9 Piece

Product Description

The SPI 13-979-0 is a 9-piece dial test indicator kit designed for precision measurement in machining, inspection, and alignment applications. The kit includes a centering indicator and a stationary face indicator, giving technicians two instrument types in a single fitted case. Measuring range extends to 2.5 inches (63.50 mm), with a dial graduation of 0.01 mm and an accuracy of 0.005 mm (0.0002 inches). The 0-25-0 dial reading format with a yellow dial face allows for quick bidirectional readings. Contact point shanks measure 1/8 inch (3.18 mm) in diameter, and the included ball-tip feelers have a 0.130-inch ball diameter.

This kit is suited for use in machine shops, tool rooms, and quality control environments where both centering and surface runout checks are performed. The set covers a range of contact point lengths - 2 inches, 4 inches, and 6 inches - accommodating various reach requirements on mills, lathes, surface plates, and inspection fixtures. The fitted case keeps all components organized and protected between uses, making it practical for bench or field inspection work.

Compatibility

Designed as a general-purpose dial test indicator kit compatible with standard 1/8-inch indicator holders, magnetic bases, and test stands used in machine shop and inspection environments.

Installation Notes

Installation and setup should be performed by a qualified machinist or metrology technician. Secure the indicator shank firmly in a compatible 1/8-inch collet or indicator holder before use, and verify zero before taking measurements. Avoid side-loading the contact tip beyond the indicator's designed contact angle range, as this can affect accuracy and damage the mechanism. Store all feelers and accessories in the fitted case when not in use to protect contact surfaces.
