Abstract
A utility service tee scraping tool having three basic components—a scraper or cutting element, a scraper holder, and an alignment body. The scraper includes a rigid, vertically oriented body to which one or more cutting blades are attached. The scraper holder includes a service pipe tee clamp having two gripping elements with surfaces adapted to fit snugly around the service pipe tee and maintain the tee scraping tool in a fixed position during operation. The tool may be manipulated from above ground. Although particularly suitable for use in keyhole excavations where remote operation of the tool is required, the tool may also be used in traditional excavations.
