At least two sleeve segments are provided and those segments are circumferentially fixed about the shank to form a substantially annular sleeve. The sleeve can be fixed about the shank in non-contacting relationship with the trailing end of the cutting tip. Moreover, the cutting tip can have a portion of maximum diameter which is of greater diameter than the inner diameter of the sleeve so that the portion of maximum diameter overlies the sleeve radially.

    Abstract: An elongate roof bolt includes a bolt body having an axially extending central bore and defining a leading end. The leading end includes a pair of axially extending abutment elements formed by machining. Each abutment element includes an abutment face for engagement with a drill tip on opposite sides thereof, to transmit rotary forces during drilling. The drill tip extends across the leading end of the bolt body and is bonded to the abutment elements by welding, soldering or brazing. The bore opens out of said bolt bonded adjacent said leading end.
