Walking around CEDIA, you'll see tools you never knew existed designed to solve problems you never knew anyone ever had. Although I've always believed that (1) you should always use the right tool for the right job,(2) you can never have enough tools, and (3) battery/electric tools are always better than ones that require my own muscle power; there are some tools on display here that even I can't justify having at home. My wife will probably say I have a hole in my head when I say I need this tool, but I can't help wanting the awesome Hole Pro Adjustable Hole Cutter drill attachment. It's capable of cutting smooth holes in all kinds of materials (dry wall, plywood, even some metal). But wait - there's more! As the name implies, it's adjustable; so this one tool can be used to drill anything from a 1 7/8-inch hole to a 17-inch hole. And the clear plastic housing not only catches all the dust and debris as you're cutting - it also serves as a support housing that makes sure you drill the hole perpendicular to the plain of the surface you're cutting. A built-in depth gauge prevents you from drilling too far into your wall and into a water pipe or speaker wire. Models range from $119.95 to $164.95 depending on the maximum size hole the tool will cut. Check out the videos of the Hole Pro in action at the company's web site www.holepro.com.
