PINPOINT LASER SYSTEMS' spindle alignment tool is simple and quick to use, with a round laser that is secured into a chuck or attached to the end of a shaft or spindle. As the laser and the receiver move relative to each other, the digital display provides a precise reading of the alignment and machine's characteristics. The tool can measure to a precision of 0.0001 in. or better, and the laser allows for alignments over distances of 150 ft. www.pinlaser.com
