A method is provided for producing multiple polycrystalline diamond and/or CBN bodies. The method involves mixing a temporary binding agent, such as paraffin, with a quantity of the crystals and then molding or extruding that mixture to produce temporarily held bodies. The temporarily held bodies are then placed in a reaction chamber and surrounded by a pressure transmitting medium, such as powdered cemented tungsten carbide. Preferably, the paraffin is removed by heat and vacuum. The reaction chamber is then pressed and heated thereby creating discrete polycrystalline diamond and/or CBN bodies of approximately the same shape and size as the temporarily held bodies. The preferred embodiment also includes the step of placing a separating layer of cobalt and graphite powder around the temporarily held bodies before they are surrounded by the pressure transmitting medium.
