Best Biscuit Joiners

The biscuit joining system was invented in Switzerland in 1956 by Hermann Steiner, who was looking for a simple means of joining wood.

The biscuit joiner, sometimes referred to as a plate joiner, is a very useful woodworking tool that can be used to join two pieces of wood together efficiently. The joiner works by using a small circular saw blade to cut a crescent-shaped hole (this hole is referred to as ‘the mouth’) in the opposite edges of the two pieces of wood.

An oval-shaped, compressed wooden ‘biscuit’ will then be covered with glue and inserted into the slot, clamping the two boards together. The wet glue will help to expand the biscuit and subsequently strengthen the bond further.

Joining wood together with a biscuit takes considerably less time than it would take to achieve strong joints manually, making it a very popular and useful tool for both hobbyists and professionals alike. 

Using biscuits to join wood is often considered to be much easier than alternative methods, such as using a dowel, so it’s easy to see why they’ve become such a popular choice.

There are numerous different models and versions available which should each do the job nicely, but it can be difficult to know which biscuit joiner is best for your needs. We’ve researched all there is to know about this power tool to help you make the best choice.

There are a couple of factors you’ll want to think about before making a purchase, including the blade size, handle style, fence features, and power source.

Best Biscuit Joiners Buying Guide

Blade Size 

Many biscuit joiners are fitted with a standard 4” blade. This blade size will allow you to cut standard slots quickly and effectively.

However, it can be really useful to select a biscuit joiner that will allow you to change blades and swap to a smaller 2” blade so that you can tackle smaller slots and use small biscuits.

Some biscuit joiners are not compatible with this smaller 2” blade so it is something to look out for to ensure your work is not limited unnecessarily. 

Fence Features 

Choosing a biscuit joiner with adjustable fence settings can be really useful for your work.

Having the ability to adjust the angle will mean that you can essentially work on either the inside or the outside face of the joint, which gives you more scope and more options for your projects.

If you can, select a biscuit joiner that will allow you to raise or lower it while staying parallel to the blade, as this will allow for flexibility without compromising on accuracy or precision. A rack and pinion mechanism, for example, can be very handy, as well as a large angle scale and locking knobs. 

Handle Style 

It’s important to pick a biscuit joiner with a comfortable or ergonomically designed handle to ensure that you can be as productive as possible.

Biscuit joiners are often available with two different handle styles; commonly a barrel grip that requires the user to hold the body of the tool, or a D-handle. The barrel grip is often regarded to be a little easier to handle as you will have a better grip on the joiner, which will give you more control as you cut.  

Power Source 

It’s always worth thinking about the power source of your chosen biscuit joiner.

Keep in mind that corded joiners will require you to remain close to an outlet or an extension cord, which could prove difficult if your work requires more flexibility. Cordless options can give you more freedom but will require regular battery charging or replacement, depending on the type of model you have. 

Frequently Asked Questions 

Why should I invest in a biscuit joiner?

Biscuit joiners can be a very useful tool to have when working with wood.

Other methods can be very time-consuming and may not be as effective. Biscuit joiners can help you to accurately line up and cut slots that you can then insert a biscuit into for a strong and secure joint.

Try to choose a high-quality biscuit joiner to ensure that your slots line up evenly and you can achieve a strong joint.
