Tongue and Groove Joint

A tongue and groove joint is a type of woodworking joint that is used to connect two boards edge-to-edge. The joint consists of a tongue, which is a protruding ridge on one board, that fits into a corresponding groove, or channel, on the other board. The tongue and groove fit snugly together, creating a strong, interlocking joint that can provide stability and support for a variety of applications.

Tongue and groove joints are commonly used in flooring, paneling, and wainscoting. They are also used in cabinetry, furniture-making, and other woodworking projects that require strong, seamless connections between two boards.

There are several different types of tongue and groove joints, including plain, beaded, and V-groove. The plain tongue and groove joint is the simplest type, where the tongue is a straight ridge that fits into a matching straight groove. The beaded tongue and groove joint has a bead (a decorative ridge) running along the center of the tongue, while the V-groove tongue and groove joint has a V-shaped groove and tongue that fit together.
