What is the primary function of a router in woodworking?

The primary function of a router in woodworking is to shape edges and cut grooves in wood. Routers are versatile tools that allow woodworkers to create decorative edges, elaborate designs, and grooves for joining pieces of wood together. They use a rotating bit that enables intricate shaping. The flexibility and precision of a router make it an essential tool for tasks like creating raised panels, inlays, and other decorative elements that enhance the aesthetic appeal and functionality of woodworking projects.

While routers can be adapted for various applications, including cutting grooves, their primary distinguishing feature is their ability to shape and profile edges of wood, setting them apart from other tools that have different functions, such as sanding, drilling, or making straight cuts in materials.
