Reed pipe descalers feature wide, tough scrapers that remove scale, dirt, and corrosion quickly from the pipe surface to allow more effective cutting, joining, gasket/valve seating or other operations. Pipe descalers are faster and more effective than chisels, chains or files and need only 2" of clearance around the pipe. Use pipe descalers to clean pipe before cutting or water tapping or drilling. Roller handles allow smoother movement in use. DS12 chain descalers are made entirely of steel that is zinc-plated for corrosion resistance and toughness. The scrapers are welded on for long life and can be sharpened.
