Abstract: Abrasive articles include a circular center member having an outer edge, a radial line, and a radial plane, a plurality of bristles extending outward from the outer edge of the circular center member and having a projection on the radial plane of the center member, the bristles comprise a plurality of abrasive particles, at least a portion of the bristles orient with the projection at a slant angle relative to the corresponding radial line. The abrasive article can have a first direction of use and a second direction of use opposite to the first direction of use, and the abrading performance achieved by the first and the second directions of use is different from each other. Robotic abrading systems can include such abrasive articles for advantageous operations. Methods of making and using such abrasive articles are also disclosed.
