Rabbet router bits cut a stepped profile along the edge of the material at a 90-degree angle, creating a rabbet joint used to join pieces of wood cleanly and securely. Rabbets are simple but strong, making them a staple joinery method in cabinet making, drawer box construction, bookcase assembly, and frame building. The resulting joint allows one piece of material to fit neatly into another for a tight, professional connection. These carbide-tipped bits are available in a range of widths to suit different material thicknesses and joinery requirements.
