摘要： A drill bit with rolling cone cutters for drilling a borehole in an earthen formation. The bit has a bit body, at least one leg depending from the bit body, a rolling cone rotatably mounted on the leg, the cone having a plurality of adjacent rows of cutters thereupon, at least one hole formed within the cone, the hole having a cylindrical wall, and a cutting element partially disposed within the hole, the cutting element having a cylindrical base which fits within the cylindrical wall of said hole, a shoulder which extends outward from the base of the cutting element, and an exposed cutting end extending from the shoulder, the cutting end being substantially symmetrical about a longitudinal axis of the cutting element.
