Abstract:
An earth-boring tool comprising a body having first cutting elements mounted to an axially leading face, the first cutting elements each having a cutting face exposed to a height above the face of the body, the cutting faces of the first cutting elements back raked and facing a direction of intended rotation of the earth-boring tool. The earth-bring tool further comprises second cutting elements mounted to the axially leading face of the body adjacent first cutting elements in a cone region of the bit face, the second cutting elements each having a cutting face exposed to a height above the face of the body and configured for a shear-type cutting action, the cutting faces of the second cutting elements back raked to about a same or greater extent than the first cutting elements and generally facing the direction of intended rotation of the earth-boring tool.
