Abstract
A drill bit with individually-balanced cutting elements. The working surface of the cutters includes a balancing feature, such as an elongate ridge, and a balancing line that extends along the length of the feature, and through the center of the working surface. The cutters are positioned in the bit so that the working surface of each cutter removes formation material in an area of cut, and so that the cutter's balancing line passes through a centroid of its area of cut. A method for making a bit with individually-balanced cutters includes positioning cutters in the bit so that a cutter's balancing line passes through a selected centroid of the cutter's area of cut.
