Abstract
A drill bit includes a drill bit body and a flexible blade positioned on the drill bit body. The drill bit further may include a cutting element coupled to and extending a distance beyond a face of the flexible blade. The cutting element may have a back rake angle and a side rake angle. At least one of the distance, back rake angle, and side rake angle may depend on a flexed position of the flexible blade.
