Just wondering, for those of you who have experience using Mothers Powerball, what is the minimum specification of a drill that still produces good results. I`ve seen cordless drills range from 130rpm - 1700rpm, and also different torque levels as well. It`d be nice to know what I need to get to make this tool effective. I actually don`t need to do any real drilling anytime in the near future so I don`t want to overbuy just for using the powerball.
Thanks
