If you enjoy DIY building projects, an impact driver is an invaluable, time-saving tool. While it might look like the typical electric power drill/screwdriver found in many homes, it actually only drives screws—but it does so with a lot more power. Because impact drivers producer more torque, they can handle larger screws more efficiently and save you time on complex wood projects. They’re also lighter and smaller than typical driver/drill combos, though they generally cost more and are a lot louder. Impact drivers are specialty items, and depending on the type of work you do, you might not need one. But if you’re building decks, pergolas, book cases, or anything that involves a lot of screws, it’s a solution that can save you time and effort and help you get the job done.
