One hub can be angularly offset relative to the other hub angularly offsetting the holes of one hub relative to the other hub from being concentric. The tufts extending from one of the radially innermost and outermost holes are stiffer than the tufts extending from the other one of the radially innermost and outermost holes imparting to the brush assembly tufts having different surface finishing and abrasive removal characteristics producing a double-stringer rotary brush having an improved blend of abrasive material removal and polishing.
