What is Router Tongue and Groove?

Router tongue and groove is a woodworking technique used to join two pieces of wood together. The "tongue" is a protruding edge on one piece of wood, while the "groove" is a corresponding slot on the other piece. When these two elements fit together, they form a tight and precise joint. This method is widely used in flooring, paneling, and furniture making, ensuring both durability and aesthetic appeal.
