Acker - Conventional Conveyor Flight Auger

With the addition of a Cutter Head, conveyor flight augers are commonly used for drilling to 100 ft. (30.5mm) depths where soil cover permits. Obviously, the sizes are many, but the most commonly used sizes are listed as standard. Cutter heads generally are somewhat larger in diameter than the conveyor flight to provide clearance for the cuttings to work easily to the surface. Optional features such as "hard facing" of the augers can be provided for added tool life when drilling abrasive formations. Flight connector pins are the drive pin type—simple but rugged. Conveyor flight auger lengths vary but 3 ft. and 5 ft. (.9144m - 1.524m) are the most popular lengths. Consult the chart for pitch and standard connections commonly used for auger boring applications. All flight augers are timed or synchronized—there are no gaps in the flight between auger sections.
