an excellent tool for joining together pieces of wood
A power tool designed to notch or mortise holes in two pieces of wood to be joined together. Biscuits are inserted into the notches along with wood glue to bind the two pieces of wood together.
If you have to make a lot of wood joints, this power tool is what you need. Use it to make complementary crescent-shape slots in mating wood pieces. The joint is then reinforced with oval splines called "biscuits" that fit perfectly into the slots. Home Improvement Encyclopedia
