A mortise machine, also known as a mortiser, is a specialized woodworking tool used to create square or rectangular holes, known as mortises, in wood. These mortises are typically part of a mortise and tenon joint, a common and strong method of joining two pieces of wood. The machine uses a powerful drill combined with a square chisel to remove wood, leaving a clean, precise mortise. Mortise machines are highly valued in furniture making, cabinetry, and carpentry, where creating strong, precise joints is crucial. They offer greater speed and accuracy than cutting mortises by hand, making them essential for professionals and serious woodworkers.
