41. A method of making a superabrasive impregnated tool comprising the steps of:
-
a) mixing a metallic matrix support material powder having irregularly shaped particles with an average particle size of greater than about 400 mesh, with a brazing alloy powder, and an organic binder;
b) placing a template having a plurality of apertures in a predetermined pattern upon a top surface of the mixture of matrix support material, distributing a plurality of superabrasive particles on a top surface of the matrix support material in a predetermined pattern said apertures being configured to hold one superabrasive particle each;
c) removing the template; and
d) binding the superabrasive particles to the matrix support material with a brazing alloy that contains between 2 and 50 percent of an element selected from the group consisting of chromium, manganese, silicon, titanium, and aluminum.
