Summary: I needed this for professional use and was shopped around for a while looking at many small rotary hammers. Considering that I only needed one for masonry drilling tasks too big for my cordless 1/2" hammer drill and occasional tile demolition anything larger than 1-1/8" was overkill for me.
Summary: We had an earlier version of this drill for 12+ years, and it performed flawlessly and did more than it should have been asked to do. Whe it finally gave out, there was no question what to replace it with. This drill is even smoother and quieter than the last. Great drill !!!
