Abstract
A method of producing a drill bit, such as for drilling a well into an earth formation, includes forming a bit body having a plurality of blades. Each of the plurality of blades includes a forward facing face with respect to a direction of rotation of the bit. The forward facing face includes individual cutter pockets at least partially recessed into the forward facing face. The method also includes securing a cutting element at least partially within each of the individual cutter pockets. Each cutting element has an abrasion resistance. Each of the plurality of blades is formed of a blade material having an abrasion resistance that is less than the abrasion resistance of the cutting element.
