What Is a Joiner?

Joiners are a tool that was manufactured to build a joint by connecting two pieces of wood. The most commonly used joints using Joiner tools are the Tenon / Mortis or concealed biscuit joints. You can cut a bird’s mouth (wood cutting design) or a slot at either end of the mitered or flat wood using the joiner. To join the pieces of wood, you need to insert the tenon or biscuit joining piece with glue into the slot. However, they’re used for biscuits joints, tenon/mortise joints, or plate joints; among these joints, tenon/mortise is the more structural and sturdier joint.

What Is a Jointer?

Jointers are different from joiners. It’s a piece of heavy-duty machinery with an infeed and outfeed table. Generally, this wood cutting tool uses a sharp cutter head to cut wood.

When you use jointers, you need to push the wood from below through the machine. A jointer is being used to make sure that your wooden board’s edges are square and straight. It can also make a twisted piece of wood smooth, flattened, and square, but you need to have good skills to do this. There’re two main jointer types available — Benchtop Jointers and Stationary Jointers.
