Vent: My brother-in-law swore by using a 4-inch auger for every post hole.

Tried it on a job with heavy clay soil in Knoxville. Spent half a day fighting it before switching to a 6-inch. Anyone else have a go-to bit size for different ground types?

Man, that 4-inch bit is a lifesaver in clay.

Remember trying to force a 4-inch through that red clay myself. Felt like I was trying to drill through a brick with a toothpick. Some days you just have to admit the bigger tool is the right tool.
