    Cutters in milled-tooth bitsare wedge shaped, while tungsten carbide insert bits feature cone-shaped cutters with extremely high strength that are press-fitted into holes in the bit body. Conversely, fixed-cutter bits feature a solid body with, in most cases, cutters made of synthetic or natural diamond.

    A drill bit (2) has a roller cone (4) with cutting elements (18) and separate, higher strength fixed cutters (8) which are fixed either axially above, below or next to the cone (4) and at such a radial position that when the drill is in operation they cut a larger diameter hole than the cone (4). As they are stronger and wear less than the cone cutters, the hole diameter is kept substantially ...
