Abstract
An improved rotary cone cutter for rock drill bits having circumferential rows of wear resistant inserts. Inserts on the two outermost rows are oriented at an angle in relationship to the axis of the cone to either the leading side or trailing side of the cone. Such orientation will achieve either increased resistance to insert breakage and/or increased rate of penetration.
