ABSTRACT:
An abrasive grinding tool and method for making the same characterized by a shaft having a longitudinal axis and a relatively thin flat bundle of monofilaments. The bundle is secured to the shaft and projects radially outwardly from two sides of the shaft in a direction generally perpendicular to the longitudinal axis. The shaft may comprise a wire having two securing sections twisted beyond the bundle to form a twisted stem. In one embodiment of the invention, the bundle has intermediate and end sections positioned generally in a plane passing through the longitudinal axis of the shaft. In an alternative embodiment, the end sections are bent circumferentially away from the intermediate sections forming a predetermined bend on each side of the shaft. In another embodiment of the invention, the securing sections of the wire stem are twisted whereby the monofilaments project radially outwardly in a helical pattern.
