A wood router is a power tool used to hollow out, shape, or cut edges in wood with high precision.
It works by spinning a very fast motor (often 10,000–30,000 RPM) that holds a cutting bit at the bottom. When you move it across wood, it removes material cleanly and accurately.
Edge shaping (rounding, beveling, decorative profiles)
Cutting grooves and dadoes (slots for joints or shelves)
Trimming laminate or flush edges
Carving patterns or lettering
Joinery work (like dovetails or mortises with attachments)
