摘要： A cutter bit for a work tool on a machine includes a leading end, conical-shaped tip portion, a rearward, frustoconical-shaped tip portion extending axially rearwardly from the leading end, conical-shaped tip portion, an annular ledge extending radially outwardly from a trailing edge of the rearward, frustoconical-shaped tip portion, a frustoconical-shaped body portion extending axially rearwardly from an outer circumferential edge of the annular ledge, a cylindrical collar portion extending axially rearwardly from a trailing edge of the frustoconical-shaped body portion, and a trailing end, cylindrical-shaped shank portion extending axially rearwardly from the cylindrical collar portion. The cutter bit may also include a plurality of circumferentially-spaced ribs projecting radially outwardly from an outer peripheral surface of at least one of the leading end, conical-shaped tip portion, the rearward, frustoconical-shaped tip portion, or the frustoconical-shaped body portion.

摘要： A shroud for a work tool is disclosed. The shroud may have a tip portion. The tip portion may have a tip extending from a shroud proximal end to a tip end disposed between the shroud proximal end and a shroud distal end. The tip portion may further have an upper leg extending from the tip end to an upper leg distal end. The tip portion may also have a lower leg extending from the tip end to a lower leg distal end. The lower leg may be spaced apart from the upper leg to form an opening between the upper leg and the lower leg. The shroud may have an attachment portion attached to the upper leg. The attachment portion may extend from adjacent the tip end to the shroud distal end.
