Biscuits or dominos are a great way to join to pieces of wood without leaving visible marks. Screws, staples and nails must be applied externally causing blemishes and other visual defects. Biscuit joining relies on cutting grooves into both pieces of wood. The proper accessories will allow biscuit and domino joiners to complete these tasks quickly. Keep your tools running smoothly with replacement cutters, blades, and fences.
