For woodworkers, bonding multiple pieces of wood is an essential part of the trade. There are many ways to fuse two work pieces together, you can do box joints or dovetails, but those joinery options alter the shape of your wood pieces. Thankfully, a biscuit joiner, also known as plate joiner, can join two wood pieces perfectly without any visible joints. You can either use a corded or cordless biscuit joiner. Corded joiners are typically seen as the more superior and efficient variant due to their heavy-duty function and more powerful motors. On the other hand, the cordless variant offers you the freedom of movement and can be used even in areas with no power. Let us compare and review the top biscuit joiners today to see which model would best fit your needs!

How Does a Biscuit Joiner Work?

Part of understanding what sets a certain biscuit joiner model apart from competition is understanding how this machine works in the first place. A biscuit joiner connects two pieces of wood together by using a small, circular saw blade to cut a crescent-shaped hole (called a mouth) in the opposite edges. Afterwards, an oval-shaped, dehydrated, and compressed wooden biscuit (beech or particle wood) is inserted in the hole and covered with glue. The glue expands the biscuit which creates a strong bond between the wood pieces.

Frequently Asked Questions

Q: Is A Biscuit Joiner Worth It?

A: A biscuit joiner offers the best bond between two wood pieces without the need to alter the edges. The biscuit placed in the mouth joins the two pieces perfectly. The glue expands the biscuit, enhancing the bond further.

The joiner not only cuts out the mortise and joins the two pieces together, but it also planes the two surfaces. It lines up the surfaces to achieve a smooth, uniform surface.

Q: Which Biscuit Joiner Is Best?

A: I highly recommend the Festool and Lamello Classic x joiners. Though they are on the high price ends, they give you perfect and accurate results. The hefty price tag is a testament to the craftsmanship and quality of materials that comes with each unit produced.

Q: What Is The Difference Between A Biscuit, Plate, and Domino Joiner?

A: Biscuit and plate joiner are names used interchangeably for the same tool. A domino joiner, although operating under the same principle, utilizes a different type of joint. Instead of a crescent shape slot, it creates a mortise and tenon joint. Elongated slots are created on opposite edges where the tenon is inserted.

Q: Are Biscuit Joints Strong?

A: Biscuits joints are not really the go-to joint when it comes to strength. They're meant to be joints that are invisible. Finger, dovetail, or domino joints offer more bonding strength. The slots' tightness is always an issue since it is easily affected by simple human errors or the machine you are using. Secondly, the biscuit does not penetrate deeply into the two pieces of wood; therefore, the joint will not be very strong.

Q: How Do You Join A Board Without A Biscuit Joiner?

A: There are a lot of joints you can use to bond two wood pieces together. The butt joint might be the simplest, but it is also the weakest. Dovetails are your go-to when it comes to achieving the tightest bond.

Final Verdict & Recommendation

I hope that you are now fully on board with biscuit joiners. As we have seen above, the joiners have many similar features and drawbacks too. Whenever you need to look for a joiner, always consider first the nature of the wood you are working on and the purpose of the end product. Though all the products reviewed above are great, I highly recommend the Festool and LaMello joiners since these joiners enable you to achieve the most precise and neat joints. Finally, always put your safety first and be careful in handling this tool.
