Patent ID: 8162081

Claim:
A downhole tool, comprising: a body comprising a first end, a second end, and a center of rotation extending longitudinally through the body; and a plurality of asymmetric blades extending the length of the body and extending radially outwards from the body, the plurality of asymmetric blades defining a passageway positioned between each of the plurality of asymmetric blades, the plurality of asymmetric blades having a direction of rotation, each of the plurality of asymmetric blades comprises a front rotational side, a blade cutting surface, and a rear rotational side, wherein the blade cutting surface of at least one of the plurality of asymmetric blades comprises: a first cutter section located on at least one of the ends of the body, the first cutter section comprising a plurality of cutter devices, each of the plurality of cutter devices exerting a radial force; and a gage section located adjacent to the first cutter section, the gage section defining an outermost diameter of the downhole tool and comprising a plurality of gage inserts, the plurality of gage inserts being substantially flushly mounted to the outer surface of the gage section, each of the plurality of gage inserts exerting a radial force, wherein the sum of two or more radial forces is a resultant radial force, and wherein at least a portion of the plurality of cutter devices and at least a portion of the plurality of gage inserts are forced balanced via an additive incremental step starting from the outermost diameter, wherein the resultant radial force for each additive incremental step is less than 10% of weight on bit at a point along the center of rotation.
