I'm planning on buying a cordless combo kit that includes the drill-driver and impact driver for some DIY projects, but was wondering if the impact driver could double as an impact wrench. Will the impact driver work well for working on my car with a socket adapter? Or would it be worth purchasing an impact wrench as well. Mostly talking about bolts under the hood or under the car, I don't need it to be able to take lug nuts off. Anyone have any experiences using the impact driver for working on the car?
