Post some pics of the auger so I can see what the teeth are like. We run just about every style of tooth there is. I can ask the drillers which style will work best for your conditions. If you have to cut the socket and tooth out completely it's not a big deal to weld in a new socket for a common style tooth. We have two welders in the shop doing it daily. The angle you choose is important and you want each tooth angle to alternate back and forth the help create some cutting action.
You absolutely will want to hard rod around the sockets and the edge of the flight. It won't take long and you'll have a 9-1/2" auger and then an 9 etc etc. They wear quick in certain conditions. We had a job recently where they'd drill a couple holes, swap augers and we'd hard rod the one while they drilled with another. Rinse lather repeat. I have access to hundreds of years drilling experience so hopefully I can help!
