I have been using 6" Post Augers from Tractor Supply. I have had to replace the first one because after a few holes the teeth and spiral tip wore down to nothing.
Now dont get me wrong and think that I just tried to drill into concrete. I have found that I have really thick hard clay under about the first foot. Of course there is small rocks like no bigger than a golf ball. Not a lot but enough to grind it down without knowing it is because I do not see the rocks often. But since the clay is so dense I have to sit and let it scrape and scrape.
So after the first fail, I picked up another to start again. The teeth wore down pretty fast in my eyes. I went to replace them and the nut had word down so we had to torch it off. I replaced the teeth and bolts and started again. Well in total I have done around 1 hundred holes and were now looking at new teeth and possible a new spiral tip.
Is there anything out there that would hold up better?
