Abstract
Methods, systems and compositions for manufacturing downhole tools and downhole tool parts for drilling subterranean material are disclosed. A model having an external peripheral shape of a downhole tool or tool part is fabricated. Mold material is applied to an external periphery of the model. The mold material is permitted to harden to form a mold about the model. The model is eliminated and a composite matrix material is cast within the mold to form a finished downhole tool or tool part.
