Abstract
A method for manufacturing a roof-bolt drill bit includes providing a bit body rotatable about a rotational axis in a rotational direction, the rotational axis extending between a forward end and a rearward end of the bit body, the bit body comprising a mounting region for mounting at least one cutting element to the bit body. The method includes forming at least one primary debris channel in the bit body, the at least one primary debris channel extending from adjacent the mounting region to a portion of the bit body located axially rearward from the mounting region, and forming at least one secondary debris channel in the bit body by machining a portion of the bit body along a substantially straight path to form an intersection with the primary debris channel.
