Claim:
A compact for an earth boring bit, comprising: a cylindrical base having an axis; a cutting tip protruding from the base, the cutting tip having a substantially flat first surface on a first side and a substantially flat second surface on a second side opposite from the first side, the first and second surfaces joining each other at a crest through which the axis extends; the cutting tip having a conical portion symmetrical in all planes about the axis and extending from the base to the first surface; an included angle between the first surface and the axis being greater than an included angle between the second surface and the axis in an axial section plane perpendicular to the crest; a convex third surface joining the first and second surfaces at a first end of the crest and a convex fourth surface joining the first and second surfaces at a second end of the crest; and the third surface having a radius that is greater than a radius of the fourth surface in an axial section plane parallel to the crest.
