Biscuit Joints are among the simplest and most effective joints in woodwork. Holes are drilled into the two pieces of wood that need to be joined and a ‘biscuit’ of compacted wood is coated in glue and inserted into them, thereby joining them securely. Biscuit jointers make it easy to reliably create biscuit joint holes of exactly the right dimensions in the correct places. They eliminate guesswork and the obligation to repeatedly take measurements when creating the holes. If you need to build a complex wooden structure with a lot of joints, investing in a biscuit jointer is a very wise decision.
