1. A method of making a superabrasive tool, comprising the steps of:
- a) providing a substrate;
b) providing a template having a plurality of apertures corresponding to a predetermined pattern;
c) placing the template on a transfer sheet;
d) filling the apertures with a plurality of superabrasive particles;
e) removing the template, such that the superabrasive particles remain in place on the transfer sheet in accordance with the predetermined pattern of the template;
f) affixing the plurality of superabrasive particles in the predetermined pattern on an exposed surface of the substrate by transferring the superabrasive particles to the exposed surface of the substrate using the transfer sheet, such that the superabrasive particles become affixed to the exposed surface of the substrate in accordance with the predetermined pattern; and
g) brazing the plurality of superabrasive particles directly to the exposed surface of the substrate in accordance with the predetermined pattern using a brazing alloy by applying the brazing alloy to the substrate and the superabrasive particles, the brazing alloy being provided as a sheet of amorphous braze, wherein the brazing alloy includes a material selected from the group consisting of titanium, vanadium, chromium, zirconium, molybdenum, tungsten, manganese, iron, silicon, aluminum and mixtures or alloys thereof.

Abstract
Superabrasive tools and methods for the making thereof are disclosed and described. In one aspect, superabrasive particles are chemically bonded to a matrix support material according to a predetermined pattern by a braze alloy. The brazing alloy may be provided as a powder, thin sheet, or sheet of amorphous alloy. A template having a plurality of apertures arranged in a predetermined pattern may be used to place the superabrasive particles on a given substrate or matrix support material.
