What is an Auger? Augers are very powerful machines with a lot of torque that can throw you like a sack of potatoes if the auger bit encounters a rock or a root. You can also navigate to this website for buying post hole augers to dig a hole.
If you only have a few postholes to dig, don’t bother. Just rent, borrow or buy the three-hand tools shown below and get to work.
You may not have many auger choices at smaller rental stores, but if you go to a larger outlet or a home center that rents power tools, you’ll have to choose between a two- or one-person (power auger head, as well as select the correctly sized auger itself.
Auger drills are interchangeable and come in 4-, 6-, 8- or 12-in. diameters. The one to choose depends on the type of posts you’re installing. Remember, the larger the diameter, the tougher it is to handle the machine.
If you’re pouring 12-in. footings for a deck, you’ll obviously need the 12-in. auger, but for 4×4 posts, pick up an 8-in. auger. You’ll be able to get away with a 6-in. auger for steel fence posts.
Keep in mind that you’ll need a larger hole (and a larger auger) if you’ll be filling around the post with concrete. The 4-in. auger will work for any small post that doesn’t need concrete poured around it.
