Spi 13-978-2 Dial Test Indicator Kit 9 Piece

Product Description

The SPI 13-978-2 is a 9-piece dial test indicator kit designed for precision measurement in machining, metrology, and quality-control applications. The kit includes both a centering indicator and a stationary face indicator, giving technicians the flexibility to handle a range of inspection tasks. The indicator measures from 0 to 0.25 inches with a dial graduation of 0.0005 inches and an accuracy of 0.0002 inches, making it suitable for close-tolerance work on lathes, mills, surface plates, and inspection fixtures. The 0-5-0 dial reading format with a white dial face supports quick, low-error readings in both plus and minus directions. The complete kit ships in a fitted case for organized storage and transport.

This kit is intended for use by machinists, tool-and-die makers, quality control inspectors, and precision measurement technicians working in job shops, manufacturing facilities, and maintenance environments. The included external feelers, internal feelers, and center point feeler cover the most common runout, concentricity, and bore-alignment checks. Contact point lengths of 2 inches, 4 inches, and 6 inches extend reach for deep-bore and hard-to-access measurement locations. The restraining arm included in the kit aids in secure indicator positioning during use.

Installation Notes

Installation and use should be performed by qualified machinists or metrology technicians familiar with indicator mounting and zeroing procedures. Secure the indicator stem firmly in the holder or base before taking measurements to prevent movement errors. Handle feeler tips carefully to avoid damage that would affect accuracy. Store the kit in the fitted case when not in use to protect contact points and the dial mechanism.
