Impact driver drill or impact screwdrivers are not for everyone. They do take a little practice to use them consistently without stripping the screw, sinking the screw too far or bending the screw and not getting it set correctly. If you do buy one and haven’t used one before, take some scrap wood and the screws you will be using and drive a few dozen to get used to how it works.
Remember, just like using your drill/driver, if you are screwing into trim, hardwoods or even thinner pieces of pine, always pilot drill the hole or you may end up splitting the wood. To make the screw go into hardwoods easier, my secret is to this is to put a little bar soap on the threads. I keep a bar of Ivory soap right with my assortment of screws.
A cordless impact driver works really well for sheet metal construction like installing a tin roof, drywall on metal studs, and metal barn siding. Most are powerful enough to drive lag bolts and sensitive enough to drive sheet metal screws into duct work. In combination with your drill/driver these impact drivers will greatly speed up your home remodeling tasks.
