Electric Tool

Electric tools are tools that operate with electric power and are used in drilling, screw-fastening, cutting, polishing, etc. They are capable of performing work more easily and quickly than by manual work. There are two types of power supply method; one is the power cord type and other is the rechargeable cordless type. The power cord types eliminate concerns about recharged power running out; however, they require a power supply to use. On the other hand, the cordless type can be used whenever and wherever as needed, but these tools cannot be used once the recharged battery runs out. Typical tools include impact screwdrivers for screw-fastening and drilling, or electric circular saws and jig saws for cutting work. Additionally, electric tools include electric sanders for polishing and electric grinders for grinding or cutting stone and metal.
