Results are presented of a theoretical analysis and a field test program to determine the relative energy efficiencies of different types of powered hand tools. First analyzed and then tested were grinders, drills and nutrunners powered by hydraulic fluid, compressed air 60 Hz single phase electricity, three phase 180 Hz electricity, three phase 360 Hz electricity and, in the case of flexible shaft tools, three phase 60 Hz power. The work included the determination of the energy use of the total system including air compressors and frequency converters where appropriate. Distribution system losses also were considered. The result of the work is that the pneumatic tools, which have become the most popular tools in industry, use between five and fifteen times more energy than the various electrically powered tools, to do the same work. Part I of the report is intended to provide an overview of the activity and a summary of the results. Part II, Investigation Reports, is the detailed exposition of the work and results. A related report, entitled Multifrequency Factory Operations, examines the potential energy savings which accrue when higher frequency electric power is used for lighting as well as tooling.
