Abstract
An insert for a drill bit that includes diamond particles disposed in a matrix material, wherein the diamond particles have a contiguity of 15% or less is disclosed. A method of forming a diamond-impregnated cutting structure, that includes loading a plurality of substantially uniformly coated diamond particles into a mold cavity, pre-compacting the substantially uniformly coated diamond particles using a cold-press cycle, and heating the compacted, substantially uniformly coated diamond particles with a matrix material to form the diamond impregnated cutting structure is also disclosed.
