These are great old rotary hammer drills! That being said, there is a risk involved. Most were used to death by contractors but there are some survivors still out there. If the switch or anything else breaks or wears out it’s junk. They are dinosaurs, parts are obsolete, and hardly no one can work on them. If you really want one as I did find a really clean one that appears to have a lot of life left in it or don’t pay much for it.
