A power tool is a tool that is actuated by yet another power source and mechanism apart from the solely manual labor used in combination with hand tools. The most typical types of power tools use electric motors. Internal combustion engines and compressed surroundings are also commonly used. Other power sources include steam engines, immediate burning up of fuels and propellants, such as in powder-actuated equipment, or even organic power sources such as for example wind or moving drinking water. Tools directly driven by pet power are not generally considered power equipment.

Power tools are found in industry, in building, in the backyard, for housework tasks such as cooking, cleaning, and around the house for purposes of driving (fasteners), drilling, reducing, shaping, electric power tools sanding, grinding, routing, polishing, painting, heating and more.

Power tools are categorized because either stationary or portable, where portable means hand-held. Portable power tools have apparent advantages in mobility. Stationary power equipment, however, often have advantages in swiftness and accuracy. A typical table saw, for example, not only cuts faster when compared to a regular hands saw, however the cuts are smoother, straighter, and more square than what’s normally achievable with a hand-held power noticed. Some stationary power equipment can produce items that cannot be made in any other way. Lathes, for example, produce truly round objects.

Stationary power tools for metalworking are often called machine tools. The word machine tool is not usually applied to stationary power equipment for woodworking, although such usage is occasionally heard, and in some cases, such as drill presses and bench grinders, precisely the same tool can be used for both woodworking and metalworking.
