A radially extending surface having an annular portion coated with abrasive elements which are arranged with respect to one another into a pattern having a first axis which is substantially oriented in the direction of relative motion between the pattern and a workpiece and a second axis disposed orthogonal to said first axis providing a substantially radially extending path for radial elimination of chips from the grinding operation. The annular portion may be broken into sectors which each offer an individual pattern. The first axis of each pattern of each sector is ideally an offset centered arrangement of elements and the second axis is ideally an aligned centered arrangement of elements. In this manner a texture is presented to the workpiece in a broad spectrum of orientations which provide for maximum material removal and maximum surface finish of the workpiece.
