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.

A method of producing a drill bit, such as for drilling a well into an earth formation, the method comprising:
- forming a bit body having a plurality of blades, each of the plurality of blades including a forward facing face with respect to a direction of rotation of the bit, the forward facing face including a first set of individual cutter pockets at least partially recessed into the forward facing face forming a first row and a second set of individual cutter pockets at least partially recessed into and exposed at the forward facing face forming a second row axially offset relative to the first row;
- and
- securing at least one cutting element at least partially within each one of the first and second sets of individual cutter pockets, each at least one cutting element having an abrasion resistance, wherein 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.
