later I thought I would have trouble using this drill bit with a Milwaukee 12V drill bit, but it turned out that the drill bit was more than adequate for a couple of holes. The drill works perfectly and is the perfect size for the starting holes. If you need large holes, such as B. for rods, I would advise you to buy several sizes to enlarge the hole. I use it for holes in a clay bottomed lawn to improve drainage, absorption and soil development on a small hard muddy bottomed lawn. Drill holes, ideally fill the holes with sand or fill with leaves/grass and clover with two to three inches of soil. Just get it. Drill a few holes if you can and this won't give you perfect results, but it will give you good results. A very useful tool.
