Abstract
A method for manufacturing a roof-bolt drill bit may include forming at least one coupling pocket in a bit body by (1) forming a pocket back surface, (2) forming a first pocket side surface including a substantially planar surface extending from the pocket back surface, and (3) forming a second pocket side surface including a substantially planar surface extending from the pocket back surface, the second pocket side surface being nonparallel to the first pocket side surface. The at least one coupling pocket may be defined by the pocket back surface, the first pocket side surface, and the second pocket side surface. The first pocket side surface may extend at an angle of between approximately 45° and approximately 90° relative to the second pocket side surface, and the first pocket side surface and the second pocket side surface may be separated from one another.
