Dan, Thanks to you and everyone for the clarification. One question on a hammer drill. Is there some type switch or something that can toggle the hammer feature on and off so if one wanted to use it as a regular drill one could? Reason I ask, is my corded 3/8 drill is on its way out and I would replace it with a hammer drill if that would give me some flexibility. I don't use the corded drill often as most times I use my Ryobi 18 volt cordless. But.... when needed it is nice to have.

You still use a masonary bit, but it cuts through most masonary pretty smoothly. Lenny explained the Tapcon screws, they look essentially like a regular screw, but with those double threads. They do come in several sizes. From something around 2 inches up to about 4.5 inches. I used those 4.5 by quarter inch TapCons and they were hell to drive in. I'd go with the 2 and 3 quarter inch Tapcons. Still gives you at least an inch and a quarter into the concrete and a bit more if you counter sink the heads. Best to get the kind with a hex head instead of philips or slotted head. Easier to drive. -- Blue skies. Dan Rossi Carnegie Mellon University.
