A biscuit joiner is one of the essential tools for joining two lumber pieces together with the help of ‘biscuits’ or thin dowels of compressed wood. Also known as a biscuit jointer, biscuit cutter, and a plate joiner, this power tool allows making professional, intangible joints required for designing cabinet doors, drawers, and other fixtures. Because there are various models available, choosing the best biscuit joiner can be daunting or confusing, particularly if you are buying for the first time. Well, this guide, along with some genuine biscuit joiner reviews, can help you choose the most suitable model as per your needs, quickly as well as smoothly.
Overview of Biscuit Joiners/Plate Joiners
A biscuit joiner is essential if you do not wish to join two wood pieces through nails, screws, or bolts. It usually has grids atop as well as at the bottom for securing the glue in place. This tool works by making inner plunges whose function is to hide the joint as well as secure the piece at its place. For joining two pieces, you often complain about spotting the joiners on the outside area of the wood. However, a biscuit joiner overcomes this issue.
With a cutting disc or a retractable blade, the tool cuts a slot in a half oval shape for the football-shaped biscuit to fit into a side of both the pieces with the help of the glue. You apply glue in the slots into which the inserted biscuits puff up and get stuck inside, delivering a strong assembly. Biscuits perform a critical task of giving strength to joints and aligning lumber pieces.
Biscuits usually are available in a variety of materials as well as sizes for joining together different types of materials, although they are often the choice for woodworking projects. The best plate joiners come with a 4-inch round blade having four to six teeth, which is replaceable by a smaller 2-inch blade for fitting smaller biscuits.

When to Use a Biscuit Cutter
Any good joiner is familiar with the different ways to join two wood pieces. Nevertheless, it is vital to know the kind of joint required as per the workpiece! The best biscuit cutter makes secure and reliable joints, which keep any lateral movement in the carved piece at bay. However, unlike other jointers, biscuit joints are used to join two pieces of different thicknesses.
A biscuit joiner is capable of rendering a myriad of invisible joints with great precision and swiftness. Listed below are a few of these joints.
- 90-degree Corner Joint: For joining pieces to be dragged in a particular direction, such as for a drawer
- Mitre Corner Joint: For gaining a clean finish for items such as boxes and furniture
- Butt Joint and Widening Joint: For joining two pieces either from edge to edge (widening) or end to end (butt), such as for a tabletop
- Frame Joint: For having a professional-looking joint
- T-joint: For joining a central area or shelf to some furniture
The biscuit joiner is handy for Do-It-Yourselfer (DIY) desiring for quick invisible joints. It is designed for cabinetmaking projects such as tabletops, small cabinets, cupboard doors, and frames. While the rendered joints alone are powerful enough to give you a sturdy structure, the tool is even used to pre-assemble pieces for further fortifying them using brackets.
You can consider buying a biscuit joiner for projects related to furniture building, post wraps, face frames, tabletops, door panels, interior, and exterior trim, furniture backs, and deck planters.
Choosing the Best Biscuit Joiner
Regardless of the price and brand, all biscuit joiner performing the same tasks without compromising with the expected level of efficiency. Considering this in mind, one can conclude that an entry-level best biscuit joiner is ideal for occasional use or a one-time task. In case of professional needs or frequent usage, a costlier joiner of higher quality and more durable ability is suggested. It is also made up of lighter materials, which is a pro for anyone who will be using it for a prolonged period.
Some minor differences do exist between the models, which are in terms of features, level of precision, and the ease with which you can adjust the numerous parts. It is essential to consider the adjustment details, especially if you need to use the tool with a high level of accuracy quite often, according to several biscuit joiner reviews.
It is rational to choose the right biscuit cutter rather than going for a popular one, as doing so gives you what you want or expect. While selecting the right model, there is a myriad of buying factors to consider along with genuine reviews by both experts and customers. Let’s consider these decision-influencing factors now.
What to Look For in a Plate Joiner
Factor 1: Your Needs
Before you go out to shop or search for any reviews, it is always wise to identify your needs and thoroughly understand them. Your needs help you in narrowing down the list of best plate joiners been shortlisted, which finally reduces confusion in selecting the right model.
For knowing your needs, you need to answer a few questions: How often you will use the tool, for what type of work you will need the tool, and what degree of precision is required, such as high or average. Once you know your needs, you now need to find the features or factors that best fulfill them. For example, if you are going to use the biscuit cutter quite often, you would need a durable tool with a sturdy design, powerful motor, least rusting parts, and more warranty.
Factor 2: Motor
So, do you plan to use the biscuit joiner quite often? If yes, then it is advisable to go with a model having a double-insulated motor, as such a motor is more durable and strong against overheating. The tool is less likely to get burned in such a condition.
Another aspect to consider is the motor size. Well, it is often thought that a bigger motor is better. However, in the case of a biscuit joiner, this is not always true. For making precision cuts, it is desirable to have a smaller motor, as it indicates less tool weight that is required for more accuracy.
The best biscuit joiners usually have 5-7 amp motor that rotates at a speed of around 10,000 Revolutions per Minute (RPMs). This blend of power and speed is perhaps the most powerful and safe one, which ensures clean and beyond satisfactory results if utilized properly.
Just keep in mind that power is always important, even if the scope and size of the project are not that big. This is fully applicable when it comes to using a biscuit joiner. As a rule of thumb, you need more power if the cutting strength you want is high. In case you wish to use the tool occasionally, go for a smaller amperage model, but hardwoods or commercial tasks, or frequent use, you require more power.
Factor 3: Biscuit Size
This is an essential factor to consider for any new woodworking project or to get the job done. You need to choose from three sizes of biscuits.
- Small (#0): These are the smallest biscuits being 5/8 inch tall and 1 3/4 inch long. You can consider them for joining smaller wood pieces or in sections without much stress that can otherwise break these small tools easily. Picture frames regularly feature such a size due to their small pieces as well as lack of stress. Such biscuits usually fit well in slim or restricted settings, such as a frame near a cabinet door in the kitchen.
- Medium (#10): These are medium-sized biscuits being 3/4 inch tall and 2 1/8 inch long. They are ideal for any project whose size is not too small or too big. You can consider them for a variety of framing projects. In most local stores, you will easily find these biscuits.
- Large (#20): These are big biscuits being 1-inch tall and 2 3/8 inch long. They are ideal for all those projects wherein much weight and twisting is required. They work perfectly with particleboard and plywood, which typically need a great deal of stress. The biggest advantage of using a large biscuit is that you have more space to put glue and a stronger hold. Such a size is usually preferable for edge gluing, and that the biscuit can extend further into each piece. However, at times, they can prove to be too big for the task.
Kindly note that all plate cutters are 5/32 inch thick, which means the only variable aspect is the oval’s width. Ideally, you need to have each size, as maximum jobs will demand different joints to be made.
As a rule of thumb, consider choosing the largest biscuit for your application if you will be working with narrower or slimmer material occasionally. Otherwise, it is best to use the biggest biscuit, as doing so will offer as much stability and strength as possible, to your joint. A majority of biscuit joiners will support all three sizes.
Biscuits have evolved significantly over the years. In today’s slots for biscuits, you can reinforce a miter, install a hinge, gather composite materials, and use knockdown fasteners, apart from using a biscuit as a clamp.
Factor 4: Type of Wood Biscuit
One of the commendable aspects of the best biscuit joiner is that a small number of biscuit sizes fulfills all your requirements. You are good to go for any joinery work if you have two or three biscuit sizes. Many people ask whether any particular kind of biscuit is more appropriate for your woodwork or project. Well, the practical reply is ‘no.’
Nevertheless, wooden biscuits are available in different variations, namely, plywood with thin layers and solid beech wood that is the most readily available and is the original one. Because of the compressed wood, any of these biscuits expand when exposed to liquid glue, for forming a strong joint. As a solid beech biscuit aims to work well with both solid planks and plywood, no persuasive reason exists to look for plywood biscuits for a task that involves plywood.
Apart from the above two options, you may even find a plastic product that employs a biscuit design for securing the joint. Due to no drying time involved, this product is faster to use. However, it is harder to spot such an item and is generally more expensive. Additionally, the joints it makes are tangible due to which you have to work more toward production rather than detailed joinery.
Factor 5: Plunge Action
Plunge refers to the initial cut, which you perform at first. This is why the plunge action is critical. So, consider the plunge action on your model and ensure that it is smooth, as a jerky action can trigger irregular biscuit cuts.
Factor 6: Blades
It is essential to have a tight blade regardless of the biscuit cutter or biscuit type you choose. This is because a loose blade can lead to sloppy cuts. For whomever precision is of utmost priority (and it should be), a tight blade is a way to go, as it involves little effort.
Additionally, you should also consider the size of the blade. The right blade size is essential to ensure an exact plunge. A biscuit joiner with a larger blade comes with more options for you to use, but at the same time, it might become a bit tough to handle.
Commonly, 4-inch blades are used in biscuit cutters, a size that is enough for making most cuts. For most DIYers and home workers, this blade size delivers a variety of cuts without using a larger cutter. However, for professional tasks and big projects, blades of six and eight inches might be needed.
Factor 7: Fences
This is another critical part that you need to look for. Fences are responsible for aligning your tool with precision. A biscuit joiner has a smart fence system for allowing you to make angled cuts. By setting the exact depth, you can easily make a plunge cut for fitting the biscuit tightly. For enjoying more flexibility for fulfilling the diverse needs of your projects, you should ensure that the fence adjustments are beyond 90 degrees.
You need to angle your tool properly to get the cut you want, which is advantageous for corner 90-degree joints, horizontal joints, and vertical joints. The fence system is such that it allows rotating the tool and locking the angle tightly for a precise cut.
Most builders consider setting the fence at 45 and 135 degrees both, which facilitates registering the tool on either the internal or external face of a mitered joint. Doing so maximizes your options while congregating pieces.
The best biscuit joiner will have a pivoting fence system, which makes it quick for you to adjust it to any angle of your choice. Moreover, it should be easy to track the fence up and down while being parallel to the blade. It is recommended looking for a rack-and-pinion system for adjusting the fence.
Factor 8: Handle
It is recommended choosing a handle with adjustable and ergonomic features. This is helpful for those with arthritis or other medical conditions with hands. Ergonomic capabilities are essential if you are planning to use the tool for an extended period of time to keep the discomfort away.
You can even go for a barrel grip or a D-style handle. A barrel grip on the tool is ideal for grabbing the tool’s body such that your hand is in line with the cut. This also helps in making it easier to remain steady while pushing.
Factor 9: Depth Halts and Stop Pins
With a standard biscuit cutter, you will usually get three plunging depths. These three sets allow setting the blade’s stopping point. This is the depth halt at which the tool will stop cutting at the allocated distance. If the tool has more depth levels, you will see the labels as S, D, and M.
With these varying levels, you can even cut homes for other things, such as a duplex hinge. However, you should remember that for having smaller cuts, it is essential to change blades. This means that you need a biscuit cutter with a blade switching option.
When the tool is at work, stop pins are required to hold the blade securely in place once you proceed to cut. In simple terms, you need to ensure that the pins have secured the blade in place, before using the tool.
Factor 10: Dust Removal
Dust is obvious, but is accumulation is not! The moment you start the cutting process, it is likely to give out dust that can be problematic for woodworking. When you work with a biscuit joiner, dust can be even more problematic. This is because it can stick inside the new channel and prevent the biscuit from fitting into it securely or fully. If the dust accumulates inside, it is essential to remove it before gluing the two pieces.
For this purpose, consider buying a biscuit cutter with a dust bag. While the blade blows the flanking air adequately to make wind, the attached dust bag gathers the additional debris. You can alternatively attach the tool to a vacuum that will grab the dust-up, while you work.
Factor 11: Center Plate
A center plate refers to a part atop the blade where the cutting work occurs. It is essential to have this feature for accurately aligning the material. It simply guarantees that the cut will go exactly where you want it to go.
Factor 12: Accessories
With a biscuit joiner, you may need one or more of the following accessories.
- Replacement Blades: Having an additional set of replacement blades is indispensable if you are thinking of adding a joiner to your collection of power tools. A standard joiner will require four-inch blades.
- Wood Glue: This should be in plenty before starting any project. After all, it is an essential ingredient for attaching the biscuit. While gluing, it is also essential to have a small brush for an even coat on the biscuit. This contributes to a tight fit once the wood section puffs up after the biscuit is in place.
- Clamping Plate: This is required for ensuring that the biscuit remains intact when the glue is drying, especially in a delicate task.
Factor 13: Brands
It is always recommended buying a plate joiner from a popular as well as a genuine brand. Such brands include Lamello, DeWalt, Makita, Ryobi, Freud, and McCulloch. Most of these brands offer models that come with interchangeable blades. Let’s explore some of these major brands.
