The PM200 Edger is a very productive, upright edging machine that works on any flooring surface. It features a removable shroud that allows for cutting right up to 1/8 inch of an edge, and an adjustable chassis that rotates the machine head to the right or left in order to run along edges on either side of machine. For use with concrete grinding & polishing. A full tool system is available from STI to perfectly prep and polish edges - go to http://www.substratetechnology.com/machines/edgers/pm200-detail for more details on the tooling. Runs wet or dry.
