A biscuit joiner, also known as a plate joiner, is a woodworking tool used to join two pieces of wood together. It operates by cutting a crescent-shaped hole (or slot) in the opposite edges of two pieces of wood. A small, oval-shaped, compressed wooden biscuit is then inserted into these slots. When glue is applied, the biscuit swells, creating a tight and strong joint. The tool consists of a small circular saw blade that is mounted on a motor. The blade is housed within a retractable guard, which is pressed against the wood to make the cut. The joiner is equipped with an adjustable fence that allows the user to set the depth and angle of the cut, ensuring precision and alignment. To use a biscuit joiner, the user first marks the locations where the biscuits will be placed on the wood pieces. The joiner is then aligned with these marks, and the blade is plunged into the wood to create the slots. After cutting, glue is applied to the slots and the biscuit is inserted. The two pieces of wood are then clamped together until the glue dries, resulting in a strong, aligned joint. Biscuit joiners are particularly useful for aligning edges, such as in panel glue-ups, and for reinforcing miter joints. They are favored for their speed, ease of use, and the strength they add to joints without the need for nails or screws.

Yes, you can use biscuits with both corded and cordless joiners. Biscuit joiners, whether corded or cordless, are designed to cut slots into wood where biscuits (small, oval-shaped pieces of compressed wood) are inserted to join two pieces of wood together. The primary difference between corded and cordless joiners is the power source. Corded joiners are plugged into an electrical outlet, providing a constant power supply, while cordless joiners operate on battery power, offering more portability and convenience. Both types of joiners use the same size and type of biscuits, typically available in standard sizes like #0, #10, and #20. The choice between a corded or cordless joiner depends on your specific needs, such as the location of your work, the availability of power outlets, and the duration of your work sessions. Corded joiners are generally more powerful and suitable for extended use, while cordless joiners offer flexibility and ease of movement, especially in areas without easy access to power. In summary, the functionality of using biscuits remains the same regardless of whether you use a corded or cordless joiner. The decision between the two should be based on your work environment and personal preferences, as both types are equally capable of creating strong, reliable joints with biscuits.
