- The standard size of a #20 biscuit:
- Length: 56mm
- Width: 23mm
- Thickness: 4mm
- A biscuit joiner is a woodworking tool used to join two pieces of wood together
- In this case it would be used to join with the biscuit #20
- A biscuit joiner uses a small circular saw blade to cut a crescent-shaped hole in the opposite edges of two pieces of wood or wood composite panels
- An oval-shaped, highly-dried and compressed wooden biscuit (made from beech wood) is covered with glue, or glue is applied in the slot
- The biscuit is immediately placed in the slot, and the two boards are clamped together
- The wet glue expands the biscuit, further improving the bond
Benefits:
- The grain direction on the biscuits are diagonal to add strength to the joinery
- The biscuit provides a quick means of getting a perfectly flush joint, while at the same time reinforcing the joint
