Abstract
An abrading tool or brush is formed with an open center low density tuft. The tufts are laterally slightly compressed and encapsulated in a medium density elastomeric foam reinforcement having a density of from about 20 to about 50 lbs/cu/ft (320-800.90 Kg/cu. meter). When the tufts are formed, preferably of wire, they are twisted about a core extending axially of the tufts. The core includes angled facets which form corners around which the wire is bent to form closely spaced bends to promote short fracture of the wire in use.
