what is a router tool used for

A router is a versatile woodworking tool that can be used to make cuts or "hollow out" a piece of wood, plastic, MDF, or even metal. It can cut grooves, make fancy edges, or help you cut patterns, which are typically used for decorative edging and finishes, giving your wood projects a more professional look. Routers can use hundreds of types of bits, each with a different purpose or decorative design, such as flush trimming, chamfer, round over, rabbeting, dovetail, and cove. Different bits allow you to create decorative picture frames, shoe molding, kitchen cabinets, doors, and edges. Routers can also cut flawless dadoes and rabbets, which are rectangular grooves cut into a board to fit another piece of wood into it and a step-shaped recess cut along the edge or the face of a piece of wood, respectively. Routers are portable, small woodworking tools, meaning that theyre very versatile and easy to maneuver during use.
