Abstract
A rotary radial wire brush made of an annular center disc hub having 32 holes circumferentially spaced apart two radially offset distances from a center about which the brush rotates with a brush wire formed of between 22 and 34 filaments or bristles providing increased material removal rates during a longer useful operating life. A preferred brush has a hub with radially outermost openings larger in size than radially innermost openings causing the brush wire anchored by its twist knot thereto to be more flexible and extend farther radially outwardly than a shorter stiffer more aggressive wire produced by anchoring via a longer twist knot to radially innermost openings. Such a construction produces a rotary brush of the invention with brush wires of alternating flexible and aggressive construction increasing surface finish and material removal rates while having increased brush life.
