An impact driver
is designed for one main task: driving screws and bolts.It is essentially a high powered screwdriver.Impact drivers use a combination of a rotating bit, like a regular drill, and a back-and-forth concussive movement to apply extra force to the screw. This enables the user to drill screws into hard materials without needing to apply as much pressure because all the hard hard work is performed by the concussive movement of the impact driver itself.
Impact drivers are particularly useful for metal work when using self-tapping screws, anchors and lag bolts. They are the best way to remove old bolts and screws from metal that may be corroded or simply stuck over time.Impacts are the tool of choice for tradesmen or serious home hobbyists who need to repeatedly drill screws into building materials because it reduces the amount of effort required and thus reduces fatigue.When used in wood it enables people to neatly embed screws below the surface of the wood without requiring counter sinking, this is a huge time saver.
An impact driver is not an impact wrench.Impact wrenches are generally powered by an air compressor and are only used to remove or fasten nuts – you can see them in use in the pitlane at any race event.
