Cordless biscuit joiners cut pockets that hold biscuits (small wood discs) to connect and align two wood workpiece edges along hidden, glue-filled joints. Biscuit joining prevents movement along the joint to keep work in alignment, especially for large pieces like tabletops, countertops, and casework. Also known as plate joiners, they create joints of different styles, such as butt, offset, and miter. They spin their circular cutting blade into one edge on each workpiece to create shared pockets for the biscuits. Their cutting height is adjustable to position the pockets, and they have different settings to cut pockets that match the biscuit size for a snug fit. These cordless tools operate in areas without access to wired power, eliminate the tripping hazard of a cord, and run on brand-specific batteries.
