HISTORY
Early industrial revolution-era factories had batteries of power tools driven by belts from overhead shafts. The prime power source was a water wheel or (later) a steam engine. The introduction of the electric motor (and electric distribution networks) in the 1880s made possible the self-powered stationary and portable tools we know today.The global market for power tools is $33 billion (in 2016) and estimated to reach $46 billion in 2025.
