What is the rabbet joint used for?

A rabbet joint is primarily used in woodworking to create a strong, interlocking connection between two pieces of material, such as in the construction of cabinets, drawers, and frames. It involves cutting a notch or groove along the edge of one piece, allowing it to fit snugly against another piece. This joint enhances stability and can also provide a surface for attaching panels or backs. Additionally, rabbet joints are often used in situations where a flush surface is desired.
