        Q:I am needing to dig a 4" diameter hole. Should I get the 4" bit or do the augers drill a larger hole diameter than themselves and would a 3" bit work better?

        Answer This Question

        A:  I would get the 8", I have both, I use the 4" for a specific need and in the end the hole is small, I use the 8" for so many things, but one interesting use is, I go around a tree stump the is 3' in diameter around the outside to dig under the roots with a trowl it makes digging a lot faster, then i "X" down the stump with chanin say and then take huge wedge and split the trump pulling out get both...What yu do is get the big one then tell spouse---oh that is not working ineed the smaller one, that wya you get both with no arguments smiling

        by|Oct 29, 2020

        A:  I would simply get the 4 inch bit. It will be a lot easier. You could use a 3 inch bit and shake and shimmy and make it bigger but you’ll have trouble getting your item shoved down into the smaller hole. Hope this helps. Jeff

        by|Oct 29, 2020

        A:  If you need a 4" hole only, then the 4" will be good. If you are needing to fill with concrete, I would recommend going larger.

        by|Nov 5, 2020

          A:  it makes the hole just a bit bigger, I bought the 4" to put 1-1/2" PVC pipe in for a garden fence, just enough for the pipe and cement around the pipe.

          The auger bit was not very effective due to the underpowered Earthquake power head. It spun much too slowly , and the bit just bounced on the hard clay.

          We are sorry to hear you are having difficulty with this machine. If the clay is extremely hard, it will be very difficult to drill through. If you would like to discuss further, please contact Customer Service at 800-345-6007 option 1, then option 5. Ardiasm

              Drilled 200 holes for planting trees. It's a little chipped up from the rocks hit during digging, but the auger held up just fine. Only drawback was that the hole at the top of the auger didn't quite match up with shaft on my auger motor, so went through a few bolts/screws that broke during drilling.

              I needed to set footings for a gazebo I was putting up on a patio made of pavers. I used a core drill to make 5" holes in patio to pour concrete. The auger worked as hoped and dug straight without hitting the sides of the pavers.

              Arrived ready to go. Used the next day. Good fit onto the drive shaft. Would have preferred standard bolt instead of hex threaded screw to keep it similar to the other bolts on the auger.
