Power tool

A power tool is a tool with a motor. The addition of the motor reduces the work that the operator has to do, and sometimes makes it possible for the operator to do things that difficult or impossible to do by hand. Common power tools include the drill, various types of saws, the router, the electric sander, and the lathe. All of these tools have manual equivalents (see hand tool).

The term power tool is also used in a more general sense, meaning a technique for greatly simplifying a complex or difficult task.
