Abstract

A drill bit (10) for cutting through a downhole metal structure includes a bit body (12) having a central axis (11) and a bit face (20). The bit body is configured to rotate about the central axis in a cutting direction. In addition, the bit includes a cutting structure (15) disposed on the bit face. The cutting structure includes a plurality of circumferentially spaced blades (16) and a plurality of primary cutter elements (40) mounted to each blade. Each primary cutter element has a forward- facing primary cutting face (44). Each primary cutter element is made of a whisker ceramic composite.
