An earth boring bit is shown having a body with one end which is connected to a drill string member for rotation and having an opposite end with a matrix formed thereon. A plurality of cutting elements are mounted on the matrix for dislodging geological formations. The cutting elements include groups of at least two but less than four cutters which are co-joined by a common backing of the matrix, the co-joined groups being spaced-apart from adjacent co-joined groups mounted on the matrix.
