摘要： A fixed-head drill bit includes a bit body having a plurality of cutting elements and at least one wear knuckle disposed on the bit body. Each cutting element includes a cutting surface defining a swept cutting profile when the bit is rotated about an axis. The at least one wear knuckle is positioned at least partially within and extending at least partially outside a selected one or more of the swept cutting profiles, allowing the fixed-head drill bit to wear into a more stable configuration.
