Quick questions
Can an impact driver be used as an impact wrench?
You can use an impact driver with a socket adapter for light bolts, but it lacks the torque and square drive for heavy-duty work. It's not a substitute for an impact wrench on lug nuts or structural bolts.
Which has more torque: impact driver or impact wrench?
Impact wrenches have significantly higher torque, often measured in foot-pounds, while impact drivers deliver inch-pounds. For example, a typical impact driver might produce up to 2,000 in-lbs, whereas an impact wrench can exceed 300 ft-lbs, making it far more powerful for large fasteners.
Do I need both an impact driver and an impact wrench?
If you do a mix of woodworking and automotive work, yes. Many professionals own both. For general DIY, an impact driver covers most needs. If you work on vehicles, an impact wrench is essential.
