摘要： A drill bit is used for drilling through earthen formations and forming a wellbore. The drill bit includes a bit body having a bit axis, and at least a first cone and a second cone coupled to the bit body. Each of the first and the second cones has a backface, a nose opposite the backface, and a cone axis of rotation. An array of cutting elements coupled to the first or second cones is in a band that lies between the backface and the nose. The cutting elements in the band are arranged at radial positions with respect to the bit axis and at least two adjacent cutting elements are at a same radial position within the array, and the remaining cutting elements are at different radial positions within the array.
