Methods for orienting superabrasive particles in a superabrasive tool are provided. In one aspect, for example, a method for orienting superabrasive particles in a tool is provided. Such a method can include providing a plurality of superabrasive particles having a preselected average size, preselecting a thickness for an amorphous braze layer to be applied to a substrate, wherein the thickness is based on the average size of the plurality of superabrasive particles, and applying an amorphous braze layer to the substrate at the preselected thickness. The method can further include dispersing the plurality of superabrasive particles onto the amorphous braze layer, and melting the amorphous braze layer to cause the plurality of superabrasive particles to rotate and sink into the amorphous braze layer, wherein the thickness of the amorphous braze layer is such that the rotation and sinking of the plurality of superabrasive particles is halted by the substrate in an attitude whereby substantially all working ends of the plurality of superabrasive particles are sharp portions. The amorphous braze layer can then be cooled to fix the plurality of superabrasive particles into the tool.
