why use a biscuit joiner
Lamello Top biscuit joiner with blade extended. Edges of 16mm Medium-density fibreboard with a #0 biscuit, set up to make a right angle joint. A biscuit joiner (or sometimes plate joiner) is a woodworking tool used to join two pieces of wood together. A biscuit joiner uses a small circular saw blade to cut a crescent-shaped hole (called the mouth) in the opposite edges of two pieces of wood or wood composite panels. An oval-shaped, highly dried and compressed wooden biscuit (beech or particle wood) is covered with glue, or glue is applied in the slot.
