  • Diamond impregnated cutting structures, earth-boring drill bits and other tools including diamond impregnated cutting structures, and related methods
    Patent number: 9567807
    Abstract: An earth-boring tool includes a bit body, a plurality of first cutting elements, and a plurality of second cutting elements. Each of the first cutting elements includes a discontinuous phase dispersed within a continuous matrix phase. The discontinuous phase includes a plurality of particles of superabrasive material. Each of the second cutting elements includes a polycrystalline diamond compact or tungsten carbide. A method of forming an earth-boring tool includes disposing a plurality of first cutting elements on a bit body and disposing a second plurality of second cutting elements on the bit body. Another method of foaming an earth-boring tool includes forming a body having a plurality of first cutting elements and a plurality of cutting element pockets and securing each of a plurality of second cutting elements within each of the cutting element pockets.
