Woodworking clamps are tools used to hold pieces of wood together securely while glue dries or during assembly. They come in various types, including bar clamps, pipe clamps, and C-clamps, each designed for specific tasks. Clamps help ensure that joints are tight and aligned, which is crucial for the strength and appearance of the finished project. These clamps are typically made from metal or plastic and can apply significant pressure. Using the right clamp for the job can improve efficiency and accuracy in woodworking projects, making them essential for both amateur and professional woodworkers.
