In one case, a honing stone has closely spaced cylindrical fibers arranged in rows of fibers substantially perpendicular to the working face, which has a slight transverse curvature, and alternate arrangements inclined relative to the face so that the ends are oval. In another case, an abrading wheel has radial fibers and another has longitudinal fibers for end-working applications. Suitable fiber materials for machining metals may be boron and boron compounds.
