A power tool is a mechanical device that operates with the assistance of an external power source and a mechanism, distinguishing it from hand tools that rely solely on manual labor. Electric motors are the most common power source for these tools, though internal combustion engines and compressed air are also widely used. Power tools play a crucial role in diverse settings, including industry, construction, gardening, and household tasks such as cooking, cleaning, and maintenance.

The functionality of power tools spans a wide spectrum, encompassing driving (fasteners), drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, heating, and more. These tools are classified as either stationary or portable, with portable tools offering the advantage of mobility. Stationary power tools excel in speed and precision, contributing to smoother, straighter, and more accurate results. For instance, a table saw not only cuts faster than a regular hand saw but also ensures precision that is challenging to achieve with a hand-held power saw.

Power tools, powered by electricity or compressed air, surpass the capabilities of hand tools by providing enhanced speed, strength, and efficiency. Their application is widespread, making them indispensable in various industries and contributing significantly to increased productivity and professional-level results. Whether in workshops, construction sites, or household projects, power tools have become essential instruments for achieving optimal outcomes.
