Relatively new to the cordless market in the past few years, impact drivers are perfect for driving deep screws, working with dense materials or in other situations that would typically put stress on your wrist. The impact system only kicks in when necessary. If more torque is needed for a task, thousands of high-impact blows per minute take over.
Otherwise, an impact driver works just like a standard cordless drill/driver - but with more power. The collet chuck requires ¼” hex drill bits, which are typically disliked by those who like keyless chucks. These tools are too powerful for simple tasks, like driving a screw into drywall. While noisier than hammer drill/drivers, cordless impact drivers can handle tough jobs while eliminating torque on your wrist or arm.
