A biscuit joiner is a tool used by woodworkers to make joints made of biscuits and glue. The tool features a rotating blade with a spring-loaded system that cuts elongated and flat biscuit-like shapes into the boards.

Biscuit joiners have limited use cases, but this has not stopped its soaring popularity. Generally used for joining two large boards together. These boards are usually sheet wood.

Biscuit joints are not the strongest since the biscuits holding them together are thin and can break easily. In biscuit joints, a shape is cut out between the two boards, and a composite biscuit material is used to fill up the shape with the help of glue.

Composite materials are compressed and dried to form an oval-shaped material called biscuit, which is ever present in a biscuit joint. While the tool cuts out the shape from the edge of the two boards to be joined, it is the biscuit and glue that holds the joint in place. A half oval shape is cut out from each board so they can form a complete oval when joined together.

Biscuit joiners cut a depth of 20mm and can support biscuit sizes of 0, 10, and 20. They typically sport rack and pinion fences that help the alignment of the cut. Some more advanced biscuit joiners use higher-quality heavy-duty aluminum fences for even better alignment.

Apart from this upgraded alignment unit, these high-end versions also have foot-activated or hand-held production units. You can choose between the corded and cordless options with each having its strong points.
