Electric tools are mechanized tools that use electric motors or electromagnets as power to drive the working head through a transmission mechanism for operation. They are usually made handheld or portable, with the characteristics of lightweight structure and easy portability. Electric tools are widely used in various fields such as construction, decoration, woodworking, and metal processing, which can significantly improve work efficiency and quality, while reducing physical labor and risks for workers.

Common electric tools include electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers. These tools can be classified into categories such as metal cutting power tools, grinding power tools, assembly power tools, and railway power tools based on their functions and application scenarios.

The development process of electric tools can be traced back to 1895, when the German company Pansion manufactured the worlds advanced DC drill. With the advancement of technology, electric tools have gradually evolved from rope tools to cordless tools, especially with the application of lithium battery technology, making cordless electric tools have significant advantages in flexibility and portability.

Overall, electric tools are indispensable tools in modern industry and household operations. They are driven by electricity, greatly improving work efficiency and safety.
