Can I use an "impact driver for concrete" to drill or drive screws in wood?
I have seen people use the impact drill for screws, they tend to deform the screw heads so that you cannot remove the screws later. For drywall that's irrelevant, for assembling something with wood, it might be. But...
Drywall screws are not a good choice for wood anyway, the shafts are thinner and weaker, because for drywall, you don't need the screws to be any stronger than the paper on the drywall. It's a LOT easier to twist the heads off of drywall screws when installing them and for them to break off afterward.
