Abstract
A substrate includes a surface having blind apertures formed therein. The blind apertures formed in the surface are preferably arranged in a regular and repeating pattern, such as with an array. A super-abrasive material fills each of the blind apertures. Each apertures hole has an opening with a cross-sectional dimension in the range of 1 mm to 15 mm. The super-abrasive material filling each of the plurality of blind apertures may be a polycrystalline diamond compact or an impregnated diamond material (such as formed by fused tungsten carbide impregnating randomly distributed diamond particles). The blind apertures may be formed in the substrate using electrical discharge machining.
