Works well in clay

I bought this auger fishtail tip because the screw type bit that new 9” auger came with kept getting stuck repeatedly in hard clay. This tip does the job but it’s kind of slow because it’s not very sharp. Also I don’t think it’s going to last long as it gets very hot to the touch. It sort of feels like a dull or cheap drill bit burning its way through wood. That being said, it’s way better than the screw type bit that came on the new auger for drilling clay. So if you have lots of holes to drill in hard compact clay soil you might want to buy a higher quality one. If your just looking to drill less than 10 holes this one works.

The bit fit the TSC auger and worked as it should

Works well with red clay soil. Tractor supply should regionally supply the proper bit for their augers. The corkscrew type auger bit that comes supplied is too aggressive and will potentially get stuck if you’re not careful. The fishtail auger will remove smaller rocks and I could go to about 32 inches without any problems.
