Abstract:
A drill bit for directional drilling includes a main body and a wear component. The main body is unitary and formed of a first material. The main body includes opposed outer surfaces and a periphery extending between the opposed surfaces. The wear component is unitary and is formed of a second material that is harder than the first material. The wear component comprises a retention portion and a wear portion. The retention portion is positioned within the first material of the main body. The retention portion includes opposed retention surfaces that, moving in a direction inward from the periphery of the main body, taper apart from each other toward the opposed outer surfaces of the main body. The wear portion extends outward from the retention portion relative to the periphery of the main body. The wear portion is substantially planar and is configured to form an outer wear edge.
