Power tools are mechanized tools powered by electrical energy. There are several groups and subgroups. Professional and household: Professional tools are designed for long-term use without interruption. They are resistant to overheating and heavy loads. Functionality, protection and convenience are more extensive. But they are significantly more expensive. On the other hand, household tools are less durable. They are suitable for those who do not want to overpay for rare use. Mains and battery power supply: The engine of network tools is powered by 220V. They are more powerful than battery counterparts and are not limited in operating time. Battery-powered tools are not connected to the mains and provide mobility, but are more expensive. Pay attention to the battery capacity, as it affects the operating time. The tool can be bought for various types of work: drilling - a drill for wood or metal, an impact drill for concrete; sawing - a circular saw for precise cutting, an electric jigsaw for curved cuts; sanding - orbital sander for large surfaces, belt sander for rough surfaces; and so on.
