Abstract
A roof bit blade insert for use in mining and other associated applications. The blade defines two opposing faces, each having a leading end and a trailing end. The blade defines an indexed protrusion disposed at either or both of the leading and trailing ends of each face. A centered protrusion is defined on several embodiments. Each of the protrusions are provided to strengthen the blade and to assist in centering the blade in a drill body slot. The protrusions defined by the leading and trailing ends of the blade are defined by either an arcuate configuration, a compound curve, an outward taper from the center of the blade, or a selected location along the leading end, to the outer edge thereof. The drill body defines a transverse slot for mounting the blade, the slot having opposing parallel faces adapted to loosely receive the blade such that it is centered therein.
