Superabrasive products

A process for the production of an engineered abrasive which comprises:

• a) forming a powder mixture of particles of a superabrasive and particles of a bonding metal;
• b) depositing the mixture as a layer on a metal foil supported on a rigid surface;
• c) applying forming pressure to the powder by means of a forming tool having a raised surface pattern, the applied pressure being sufficient to cause the powder and the metal foil to form a coherent sheet having first and second major surfaces, wherein the first surface has a raised pattern comprising a plurality of metal/superabrasive composites wherein the pattern is the inverse of the pattern on the forming tool, and the second surface is smooth;
• and
• d) sintering the metal particles in the composites to a porosity of the structure that is less than 20%.
