A biscuit jointer is used to cut accurate recesses into wood. A small blade cuts each hole, and the different pieces are joined together to create a strong joint. This is a highly skilled method of joining two or more pieces of wood together. When done correctly, there’s no need to use any nails, screws or glue. If you build furniture, you’ll need a biscuit jointer you can rely on. There are several features to look out for, including an adjustable fence for multiple cutting angles.
