Abstract
Compacts are oriented in certain places on roller cones of an earth boring bit to increase the number of compacts in certain rows. The compacts that are pressed into holes in rows on the cones. The compacts are of tungsten carbide and have a cutting end axis and a barrel axis. The barrel axis intersects the cutting end axis at an obtuse angle. In one of the cones, the barrel axis of at least some of the compacts is rotated to have less inclination than the barrel axis of the compact nearest to it. The nearest compact may be in the same row or an adjacent row. Also, at least some of the compacts may be asymmetrical, with a cutting end axis that diverges from a barrel axis.
