A mortiser is a specialized device or machine designed to cut precise square holes, or mortises, into wood. This tool is essential for creating mortise and tenon joints, a traditional and highly durable method of joining two pieces of wood. In this technique, one board has a square slot (the mortise), while the other features a matching square projection (the tenon) that fits into the slot.

Mortisers come in various forms, including bench-mounted and floor-standing models, and are known for their ability to produce clean, accurate cuts with minimal effort. By using a mortiser, woodworkers can achieve strong, stable joints that are perfect for furniture making, cabinetry, and other woodworking projects.

Whether you're a professional or a hobbyist, a mortiser simplifies the process of creating these essential joints, enhancing both the efficiency and quality of your woodworking tasks.
