Abstract
A rotating bit with cutters used in drilling operations to advance a borehole in the earth. The bit includes column cutters in the bit body in a recessed central area. The column cutters contact a column of borehole material that is formed during operation. The column cutters are oriented to fracture the column, producing larger cuttings or chips, and to exert a force on the column to limit lateral movement of the bit during operation.
