If you are in the woodworking business or enjoy making your own furniture at home, a biscuit joiner is a tool that will make your life much easier when it comes to joining two pieces of wood together. These tools are also known as plate joiners, use small saw blades to cut crescent-shaped holes on the two opposite sides of the wood pieces or panels.
Then the compressed and highly dried oval biscuits, which are covered with glue, are used to attach the two wooden parts. Since the wet glue helps the biscuits expand, the bond between the parts strengthens.
