This 1/2-inch, 10-Amp Dewalt Hammer Drill works strong and perfectly.
I've used it for a handful of DIY projects like putting a floor receptacle in my slab and glass clamps in a Corian shower base.
But concrete's no fun, cutting or drilling, and I don't plan to do anything else that'd need a hammer drill or anything close to this powerful, so it's yours if you want it.
Any questions, please ask.
And stay well.
