A biscuit joiner, also known as a plate joiner, is the quintessential tool for joining two pieces of wood. The biscuit joiner carves a mortise into a workpiece for a biscuit to be placed inside it. Once the biscuit is in place and your inside edges are prepared with glue, another workpiece with a corresponding mortise is joined to the latter piece. This system locks the two independent pieces together to create one piece.

The Motor Is Important

You want to make sure that your biscuit joiner has a good quality and powerful motor that runs at 10,000 rpm or higher. You also want to make sure that your holes are cut without any blade resistance; the last thing you want is your workpiece to move out of place during cutting.

Get A Good Fence System

Make sure to get a joiner with a good fence system. A good fence system makes it easy to line up and square your cuts. Finding that your mortises donโ€™t line up when youโ€™re joining is an extremely tragic event youโ€™re best to avoid.

Get something with a warranty if you can. Lastly, dust collection capability is handy, but not a deal breaker.
