A router machine is a tool used in woodworking to hollow out areas in the surface of a material or create decorative edges. With its spinning bit, the router is capable of shaping edges, creating grooves, and making intricate cuts with precision, making it popular in cabinet making, furniture production, and decorative woodworking projects.

Routers are typically handheld or table-mounted, with adjustable bases for varying depths and angles of cuts. This adjustability makes it possible to craft detailed shapes, such as beveled edges and inlays.
