If you are into professional woodworking and carpentry, you would know the importance of having a reliable power tool to make your work easier. While you usually work with power saws, drill machines, sanders, and other power tools, you can also make use of a plate joiner when it comes to joining different pieces of wood together.
A plate joiner is a handy power tool that is fitted with a circular saw and helps you cut a circular hole into the surface of the wood pieces, which can then be joined together with the help of a wooden disc, which is also called a biscuit and slides into the holes of both wood pieces when they are placed together. This is why plate joiners are also called biscuit joiners.

Best Plate Joiners Buying Guide
What is a Plate Joiner?
A plate joiner, or biscuit joiner, is a power tool used by woodworkers to cut slits or circular holes in different types of wood, and its primary purpose is to provide a stronger and more secure bond between two workpieces that have to be joined together, and wood ‘biscuits’ are slid into the holes created by the joiner for this purpose.
Plate joiners are particularly useful power tools for carpenters and woodworkers, as well as DIY enthusiasts who like to join different pieces of wood together to create furniture or other accessories. The machine makes the holes using a circular saw mechanism, and has a sharp round blade fitted inside it, which is pushed forward by the motor into the material.
Plate joiners also contain a rack and pinion fence, which allow you to set the height at which you want to make the hole in the wood piece, as well as an angled fence that lets you adjust the angle of cutting. This makes the plate joiner suitable for making holes for all types of joints, including miter joints, corner joints, and many others.
How to Use a Plate Joiner?
A plate joiner helps you make joints between two wood pieces much stronger than they would be by just using glue. It requires a certain level of practice before you can start using it perfectly, but it isn’t impossible to learn. To start with, you can line up the pieces of wood that have to be joined together. Make sure that their grains are facing the same way, and they are placed in the same direction in which they will be joined.
Next, use a pencil to mark the places where you want to make the biscuit cuts. Once you have marked the places, the next step is to select the depth and angle of the cut on your plate joiner. Then, grabbing the handle of the plate joiner, guide it towards each piece of wood, with the line of the fence coinciding with the markings you have made. Turn the joiner on and push it towards the wood, which will cut a hole into the surface.
When the hole is cut properly, the blade will retract and spin idly, following which you can turn it off and remove it. Repeat these steps with each cut you have to make. The last step is to apply glue on the biscuits and place them inside the holes, and clamp the pieces together to allow them to stick perfectly.
Things to Consider Before Buying a Plate Joiner
There are numerous factors that you should keep in mind whenever you have to choose between various plate joiners. Here are some of the key factors that you should apply.
Just like most power tools, plate joiners also come in corded and cordless variants. While corded options are more powerful and have a higher cutting speed, cordless plate joiners offer more convenience and portability. Plus, you can also carry them with you for various woodworking jobs, and you also don’t have to worry about snagging or tugging on the cord while working.
Make sure to choose the one that suits your style of work better, so that you don’t have to compromise anything when you are using it to make biscuit cuts.
Most plate joiners have 4” diameter blades, which are sufficient for creating a large enough hole to fit biscuits of different depths inside it. However, if you are looking to make smaller cuts, you may be able to find plate joiners that are also compatible with a 2” diameter blade and you can easily switch the blades.
Cutting depth is one of the key factors, and most models of plate joiners have preset levels to choose from, such as #0, #10, and #20. These are the most common biscuit sizes, and they allow you to quickly set the depth. Moreover, some models also allow you to set custom cutting depths, and they are suitable if you know the depth you require in your projects.
The motor of the plate joiner is responsible for its speed, and the higher the cutting speed, the smoother and more precise its performance will be. Most plate joiners have a cutting speed of 10000 or 11000 RPM, which is suitable for cutting through harder materials as well. Plus, this cutting speed is sufficient to prevent overheating, which is often caused when the blade works slowly. If you have to make smaller cuts or are working with softer materials, then you can afford to have a plate joiner with a lower cutting speed.
Although this may not seem as important, having an ergonomically designed handle makes all the difference when you are operating a plate joiner. Typically, you can find two types of handles in plate joiners: D-type and barrel type. The D-type handles have the trigger close by, which allows for better speed control, whereas the barrel type handle is installed closer to the fence, which enables you to have better control over the machine. Make sure to choose the handle that you can hold comfortably.
Plate Joiner FAQ
Q: What is a suitable cutting speed for plate joiners?
Ideally, you should choose a plate joiner that delivers a cutting speed of at least 9000 RPM, as this makes it suitable for cutting holes in harder materials.
Q: How deep can a plate joiner cut?
Generally, you can cut as deep as ¾” with a plate joiner, and you can fit #20 biscuits into the hole perfectly.
Q: How do I decide the number of biscuits to put in a piece of wood?
The best way to ensure maximum strength between two pieces of wood is to leave a space of 6” to 8” between each cut. This is sufficient to allow the two pieces to stick together strongly.
