Review on 2 Set Garden Auger Drill Bits For Planting, 3/8" Hex Drive - 3"X12", 1.6"X16.5 by Daryl Fitch

Hooked it up to my Dewalt cordless drill; and really dig it! (pun intended) your mileage may vary based on the soil you are trying to get into; for example, once I was careless enough to drive it into the ground with a single hand (Terrible mistake, don't try this at home) the bit caught up to a rock and the force of my drill twisted my wrist like a rubber band.Please be careful and control your drill speed and always try to drive it with two hands.Another tip I found useful, don't drive it as if you were drilling a hole in pine, instead go in more or less slowly and try holding it at a certain depth so it pulls dirt out instead of simply going into the ground, it also helps if you keep getting it in and out while the drill works so you pull dirt out faster.Over all if you are careful and patient, you will be able to dig almost 2 feet deep wholes for whatever you want to plant in less than 30 seconds.If your soil is too rocky you may have different results so please be careful.
