Abstract
Segmental grinding wheel for forming the tip of intersecting surfaces on tools includes an array of peripherally extending and circumferentially, spaced segments. Each segment includes first and second grit-coated angularly oriented grinding surfaces. Another array includes similar grinding segments which are interdigitated in alternating sequence with the segments of the first array. The segments of the two arrays are concentric and partially coextensive in the axial direction of the wheel so that the plane of rotation of the first grinding surface of each segment in one array intersects the plane of rotation of the second grinding surface of an adjacent segment in the other array along a line which represents the tip of the intersecting surfaces.
