If you handle some or most of your own home maintenance chores, or you enjoy DIY home improvement projects, chances are you either own or are considering the  purchase of an impact driver.  While many people equate these with power screw drivers, they are not the same.  If you've wondered when you should use an impact driver or opt for a drill or power screw driver, here is a great article from This Old House.

While impact drivers offer advantages other drivers and drills don't, they are quite a bit more expensive, not to mention noisy, so you should be convinced that this is the tool you really need before making an investment in it.  Drivers are available in both the gun and wand models, and from a number of tool manufacturers.  Read this article before you buy.
