DRILL BIT

Abstract

An improved drill bit is a drill bit designed for use with a drain snake unclogging apparatus for sewer pipes having an arrowhead shaped point attached to a short drill bit sized for sewer pipes and having helical grooves along its length for material that has been cut or loosened by the pointed chisel bit to move rearward through the grooves away from the clogged material. The bit is more effective for solid plugs within a pipeline in that it cuts the clogging material into pieces instead of being design for gripping and pulling the clog.
