The edge cutter bit assembly (40) includes a plurality of holders (42). Each holder (42) has a bore (50) for holding a non-rotatable cutter bit (70). The holders (42) are oriented with respect to the drum (22) so that at least a portion of each one of the cutter bits (70) extends past the edge of the drum (22).
