I used this auger to drill about 35 holes for fence post sleeves in extremely hard, poorly drained clay soil during a drought year using a 1/2 inch hammer drill. It worked well right up until the end when the shaft snapped off at the drill chuck. When it hit even harder soil below, it would bind and the drill would torque my hands, but the auger held steady, until that happened. I continued to use it anyway and it still works, but is a little shorter. It does wobble, but that wasn't really an issue once it got into the ground a few inches. The tip and auger spirals lost paint, but otherwise held together and worked well. I may order another.
