Quick Summary

A power tool is a hand tool or portable tool driven by a power source, distinguishing it from stationary tools like a drill press. While typically powered by electricity, the category also includes tools powered by compressed air, such as air impact wrenches. Gasoline-engine-driven tools are excluded.

Common power tools include electric drills and circular saws. Many modern power tools, like sanders and polishers, are built around the electric motor. Production of power tools increased significantly after World War II, with many now used in home workshops. Metal-cutting power saws, such as band saws and circular disk saws, are also important industrial tools.12
