"Hammer Drill" or "Rotary Hammer Drill"? The first is a worthless piece of junk. The second is miraculous. Rotary Hammer Drills use SDS bits with carbide tips. The regular hammer drill uses round carbide tipped bits in a regular drill chuck. The Rotary you can drill any size hole in any concrete in seconds or so. Great for attaching conduit and electrical boxes to your concrete basement walls. My number one use for my Makita rotary hammer drill. My Makita is a 1 1/8" model. Around $200 retail. All tool companies make a 1 1/8" model around $200. Mine came with a free Makita 4.5" grinder when I bought it about 15 years ago. I guess it was free.
