Before I bought my magnum hole shooter I had gone through several skil and crapsman drills and saws. When I got the milwaukee My tool buying changed forever. No more junk ever! That was many moons ago and it just keeps on going and going. I will never sell my old magnum drill. They have a new one out with even more power and torque and a nice rubber grip which I'll probably buy but I'm still keeping my magnum. It runs as smooth today as it did 15 years ago. I've done everything with it from drilling wood and steel to Mixing concrete. It won't drill concrete but it will sure mix it like no other. It also mixes drywall mud very well. As others have said it is very powerful and it will hurt you if you are not careful. I got thrown off a ladder once when the bit caught and I wasn't going to let go. I thought it was going to rip my hand off. but it didn't . After that I always treated it with more respect. This unit comes with a lifetime warranty . No other manufacturer that I know of stands behind their tools like milwaukee. It's no wonder when you consider their incredible track record.
