Title: Hammer Drill?
Review: I bought one, tried to drill a 5/16" hole (half the rated capacity) in concrete with a new masonry bit and smoked the bit. The drill is too fast, even on it's lowest speed to effectively drill holes in concrete, maybe concrete blocks, but not concrete. I took it back 20 minutes after trying to use it. I have other Hitachi products that I am happy with, but not this one. If you want a hammer drill, keep looking, this isn't one...
