Earth-boring bit with shear cutting elements

An earth-boring bit, comprising:

• a bit body having a bit axis of rotation;
• at least one cone carried by the bit body for rotation relative to the bit body about a cone axis, the cone having gage surface and a nose area separated by a central area;
• a plurality of rows of central area inserts mounted in holes in the central area of the cone, each of the central area inserts having a cutting end protruding from the cone;
• and
• a nose insert in the nose area, the nose insert being closer to the bit axis that any of the central area inserts, the nose insert having a barrel located within a hole in the nose area and an outer end separated from the barrel by a conical surface, the outer end having a circular perimeter that is in a single plane.

An earth-boring bit, comprising:

• a bit body having a bit axis of rotation;
• first, second, and third cones carried by the bit body for rotation relative to the bit body about a cone axis, each of the cones having gage surface and a nose area separated by a central area;
• and
• a nose insert in the nose area of each of the cones, each of the nose inserts having a barrel located within a hole in the nose area of one of the cones, a conical surface protruding from the hole, and an outer end bounded by the conical surface, the barrel having an axis that passes through the outer end normal to the outer end.
