What is a Biscuit Joiner?

A biscuit joiner is a tool used in woodworking to join together two pieces of wood. It leaves a professional look on edges such as those on picture frames and cabinets. Used in conjunction with "biscuits," this tool is a must-have for hobby enthusiasts and handymen.

How it Works

The joiner cuts slots in the wood where two pieces are then to be joined. A biscuit is placed in the slot to create a secure joint between the pieces.

What's a Biscuit?

The biscuit is a rounded or oval piece of wood, typically made from beech wood. Used with woodworking glue, it provides a strong joint between two large pieces of wood.

Why Beech?

Beech wood is known for its strength and durability. The pressed laminate pieces are designed to expand when they come into contact with the glue for a tighter fit when wedged.

How's the Joiner Cut?

The wood is held against a fence on the joiner for support and stability. The blade then cuts a semi-circle in each piece to later be filled by the biscuit.

Joiner Maintenance

The blades, or cutters, on the biscuit joiner tend to wear down quickly. They should be replaced after a few times of sharpening when the thickness begins to be lost.

Uses of the Biscuit Joiner

As well as the aforementioned items, these joiners are used for a variety of objects. Edges on shelves as well as other household items could benefit from a clean edge these tools provide.
