A power tool is an instrument that’s actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power equipment use electric motors. Internal combustion engines and compressed atmosphere are also commonly used. Other power resources include steam engines, direct burning of fuels and propellants, such as in powder-actuated tools, or even organic power sources such as for example wind or moving water. Tools directly driven by animal power aren’t generally considered power tools.

Power tools are used in industry, in building, in the backyard, for housework jobs such as cooking, cleaning, and around the house for purposes of generating (fasteners), drilling, trimming, shaping, sanding, grinding, routing, polishing, painting, heating system and more.

Power tools are classified as either stationary or portable, where portable means hand-held. Portable power equipment have obvious advantages in mobility. Stationary power tools, however, often have advantages in acceleration and accuracy. A typical table saw, for electric power tools instance, not only cuts faster when compared to a regular hand 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 objects that cannot be made in any other way. Lathes, for instance, produce truly round items.

Stationary power tools for metalworking are usually called machine tools. The term machine tool is not usually put on stationary power equipment for woodworking, although such utilization is from time to time heard, and in some cases, such as drill presses and bench grinders, specifically the same tool is utilized for both woodworking and metalworking.
