 You know, I actually did tackle a stump that way. I drilled deep holes into a stump, and you know what I learned? You can't do that with a small drill because you burn your drill out. It was smoking in my hand, and I actually completely burned it right out. So I threw that one in the garbage, and I actually got out one of my old corded drills. One of the things I guess the corded drill was good for is that, and I was able to get all the holes drilled. And it worked very well. Just like you say, it takes a while, but it does work.
