Abstract: A tool bit is disclosed. The tool bit may comprise a threaded portion, a shank, a shoulder, an anti-rotation segment and a working portion. The threaded portion may be centered about and extend longitudinally along a first axis. The shank may be centered about the first axis and extend longitudinally along the first axis. The shank may be disposed between the threaded portion and the shoulder. The anti-rotation segment may be disposed between the shoulder and the working portion of the tool bit. The working portion may be oriented to extend lengthwise away from the first axis and to extend lengthwise along another axis that is transverse to the first axis. The working portion may include a planar cutting surface that includes a working edge. The planar cutting surface may be oriented transverse to the first axis.
