The function of a biscuit joiner is specifically designed to cut slots in wood for joining pieces with biscuits. Biscuits are thin, oval-shaped wooden pieces that fit into these slots to reinforce the joint between two pieces of wood. When the biscuit is inserted into the slot along with glue, it swells to create a solid bond, providing a strong and stable joint.

This tool is essential for ensuring precise alignment and creates a flush surface between joined pieces, making it particularly useful in cabinetmaking and other woodworking projects where clean, strong joints are required. The biscuit joiner allows for a quick and efficient method of creating these slots, which contributes to the overall quality of the finished product.
