The JESS Tools 18" to 36" belling auger saved concrete and labor starting with the first job. It also allowed our guys to work smarter and safer than before when we had to dig 36" diameter post holes for large footers and work in and over these large holes to set the poles. We were impressed by the ease with which the auger cut through the hard clay we were into as well as how efficiently it emptied between each run in the hole. We are delighted that we made the investment for this very effective piece of equipment.
