Good motor, bad auger quality

11 months ago
The quality of the auger bit is poor. The replaceable carbide bits that bolt onto the auger were previously used as they were scratched and the nut and bolts were rusty. On the third hole, it hit a rock and the weld that holds the 2" hex head adapter to the round shaft twisted off. The weld is very poor, a soldering gun could have done a better job. As an improvement, there could be bolts that hold the hex head to the shaft.
