Abstract
A design for a drill bit (10) is provided. The design permits placement of a plurality of cutters (14) in a pattern approaching an ideal equal volume cutting arrangement while minimizing the mathematical steps necessary to calculate the desired positions. The design positions the cutters so that the annular area between radially adjacent cutters is a constant. Certain groups of cutters can also be positioned to prevent a central core in the material drilled and to provide a desired kerf overlap.
