To add and FWIW I bought my first Impact Driver in 1970 when Japanese motorcycles started to become common the Phillips screws on these were impossible to remove without this tool. The term *Driver* has always referred to a screwing function so I don't think it that unreasonable now that an Impact function has been added to a drill/Driver but with only a screw bit chuck that it should be called an Impact Driver. YMMV
