A drill adapter is a tool used to convert a power drill into a different type of tool. It consists of a shaft that attaches to the chuck of a drill and a different tool or accessory that attaches to the other end. Drill adapters are available for a variety of applications, including screwdriver bits, socket wrenches, sanding discs, and wire brushes, among others. They allow the user to utilize their power drill for a wider range of tasks, saving time and money on separate tools. It's important to use the correct drill adapter for the intended application and to follow safety guidelines when using power tools.
