Abstract: A radial brush having a plurality of discrete brush segments mechanically affixed to or mechanically affixed to and bonded to a central core. Each brush segment is a preformed discrete component having a predetermined degree of splay. The brush segments are affixed to the core for rotation about an axis of rotation, so that splay of the individual fibers lies in a plane orthogonal to the axis of rotation and splay in the axial direction may be precluded.
