Best Biscuit Joiner/Plate Joiner

When you are in the wood business, it’s only a matter of time (and dedication, we might add) until you get familiar to all the tools you need to perfectly work the wood.

Therefore, eventually you get to use the biscuit joiner, aka the “plate joiner”. For those of you who don’t know by now, the biscuit joiner is a woodworking tool that helps you join two pieces of wood together.

The basics

Let’s make a short description on how a plate joiner actually works. A small circular saw blade within the biscuit joiner cuts a crescent-shaped hole (also known as “the mouth”) in the opposite edges of two pieces of wood (you may also use some wood composite panels).

A compressed wooden biscuit (that is oval-shaped and also highly dried) is covered with glue. In some cases, the glue is applied in the slot. You place right away the biscuit in the slot and the two boards are attached together. As the wet glue expands the biscuit, the bond gets also increased.

There are many job applications for the biscuit joiner. You use it when joining sheet goods: particleboard, plywood, medium-density fiberboard.

If you want to do things easier, without losing the strength, you may also use some solid wood, not use mortise, and tenon joints.

You get to use the plate joiner when you want to align pieces of wood, as they are joined edge-to-edge so that you can obtain wider panels.

No matter the job, keep in mind though using the same face when cutting the slots, as you want the boards to be the same color. Even if you used the best biscuit joiner out there (no, there is no such thing!), your work is in vain if the boards aren’t the same flush.

You may also use the biscuit joiner to align edges of your work pieces (say you want to make a 90-degree angle between your work pieces). It’s the biscuit joiner that helps you get the perfectly color joint, providing reinforcement for the joint at the same time.

There are many types of biscuit joiners out there, and you can decide for yourself if you need metal connectors or hinges. All joiner reviews highlight though that biscuit joiners are highly portable and versatile, more than anything else is.

How to choose?

There are some things to consider when you are shopping for a biscuit joiner and power is the most important aspect.

The more power the joiner gives, the more cutting strength you get. It’s quite obvious that you don’t need a beast if you only use it once a year. A smaller amperage unit would do it in this case. Nevertheless, if you use the biscuit joiner on regular basics, don’t hesitate to get a powerful tool.

You can’t talk about power without minimal consideration for the motor. The main rule is that a tool that is used very often should feature a double-insulated motor. This provides longer lifespan to the motor and the risk for overheat is minimal.

The initial cut on of the biscuit joiner (also known as “plunge”) is essential so look carefully when shopping. You want a tool that comes with a smooth plunge, that doesn’t cause uneven cuts.

And now we talk about cutting, we also need to remind of the blade that should be tight all the time. After all, you want accurate cuts all the time, right?

No tool is useful if it’s not comfortable to use. In the case of biscuit joiner, the handle should have several features for adjusting. You want an ergonomic design on the handle that ensure minimal strain, no matter how long you use the joiner.

Now that you know all these tips and info, you’re only one-step away from finding the best plate joiner for you and your needs.
