A rotary tool (also known as a die grinder), is a handheld power tool used across trades such as woodworking, metalworking, and construction. Some of the tasks that require rotary tools include sanding, carving, routing, grinding, drilling, and polishing, among others. In addition, rotary tools are also useful for household tasks such as repairs and maintenance.
