As a woodworker or DIYer, there are certain essential tools that, once the DIYer discovers them, help unlock their real potential. Among those tools is the trusty biscuit joiner. This power tool helps make creating strong joints and large, flat surfaces easier—and produces better results.
Whether it’s for gluing up a new worktop for a shop bench or building a bookshelf from scratch, the best biscuit joiner can help. These handy tools use small, circular saw blades to cut slices in two pieces of wood, allowing woodworkers to insert a biscuit (a small, football-shaped chunk of compressed wood) in the two slots to create a solid joint. The glue-covered biscuit then expands, locking the two boards together and creating an incredibly strong joint that glue alone can’t match.

What to Consider When Choosing a Biscuit Joiner
Once a DIYer gets their hands on a biscuit joiner, they might wonder how they ever finished woodworking projects without one. They’ll no doubt come to rely on it a lot, so choosing a quality model is key. Here’s what to keep in mind when shopping for the best biscuit joiner.
Size and Weight
Usually, the larger and heavier the wood biscuit cutter, the better the quality of its parts, and a bruiser of a biscuit joiner will likely have a heavy-duty motor and high-quality slides (which guide the blade while it cuts to provide consistent results). However, a heavy biscuit joiner or a super high-end tool isn’t necessary or even ideal for everyone. There are plenty of midrange options weighing around 5 or 6 pounds—about half the weight of a high-end model—that will do the trick.
Determining whether a burly biscuit joiner is necessary will come down to the types of projects and how often the joiner will see use. For the overwhelming majority of DIYers, a midrange biscuit joiner will handle materials like oak and maple without issue. For those working in a cabinet shop and putting a joiner through its paces daily, consider the heavier-duty options.
Corded vs. Cordless
As with all power tools, the debate of corded versus cordless exists in the biscuit-joinery world. Deciding on a style often just comes down to personal preference.
Almost all biscuit joiners are corded. Since most woodworking projects take place in a workshop, there’s usually power readily available. Also, it’s not typical to be climbing a ladder or working under a cabinet with a biscuit joiner, so portability isn’t really an issue.
Biscuit joinery puts quite the tax on a battery, so most manufacturers haven’t taken the dive into cordless joinery. However, there are a few cordless biscuit joiners available. These can be quite handy during projects like kitchen remodels, where the user might need to join two sections of wooden countertops and would prefer not to set up an extension cord.
Power and Speed
Biscuit joiners need to be stout power tools with tough parts and plenty of power and speed. While it might not take much power to bore a hole in pine or cedar, plunge cutting a section of hickory or walnut can be a challenge.
The most important power-related factor to consider when shopping is a biscuit joiner’s amperage rating. Amperage refers to the current load a motor can handle before its parts start to fail. This has much to do with the quality of individual components inside the tool and how well it can cool itself while running. Ideally, look for a model with 5 to 7 amps.
When it comes to actually getting the work done, speed matters as well. The faster the motor, the faster it can spin the blade and cut a biscuit slot. Look for models with rpm ratings between 8,000 and 10,000 for good general use.
Biscuit Size
Biscuit joiners use biscuits to join workpieces together. When the user inserts a glue-covered biscuit into a slot, it locks in to join two workpieces as one. Biscuits come in small, medium, and large sizes (#0, #10, and #20, respectively). To accommodate different-size biscuits, most joiners have settings that adjust for deeper or shallower cuts, some cutting as deep as ¾ inch; other models may require a blade change.
While biscuit size might not be a factor when shopping for a biscuit joiner, it can be important while working. For example, bookshelves and countertops might require a lot of gluing surface—and a bigger biscuit—while only a smaller biscuit might fit in a cabinet face frame.
Blades
Although biscuit joiners use circular-shaped saw blades, they’re quite a bit different than the blades found in a miter, table, or circular saw. They’re thicker, with much fewer teeth, and they’re much smaller in diameter.
Burrowing a spinning blade into dense hardwoods over and over again builds up quite a bit of heat and pressure, so blade material and longevity matter. Most biscuit joiner manufacturers use carbide-tipped blades, as they stay sharper longer than a lower-end steel blade, particularly for denser materials like walnut and hickory. They also hold up better to the speeds of high-end biscuit joiners.
Cutting Angle and Depth
One feature most woodworkers appreciate about biscuit joiners is the tools’ versatility. The adjustable cutting angles provide the ability to cut slots in a wide range of situations. While edge joining two boards is the most obvious use for biscuit joiners, they can also bore biscuit slots for mitered corners and angled joinery or slots in the field of a workpiece for shelves or other uses. This is thanks to their adjustable fences, which users can set for a particular angle to bore an accurate slot.
Adjustable cutting depth is also an important feature. Swapping between preset depths allows users to use different biscuit sizes quickly without worrying if the joint will be tight or hold enough glue.
Handle Type
When choosing the best biscuit joiner for a workshop, consider handle preference. There are two main styles: barrel handles and D-shaped handles.
Barrel-style handles can facilitate precise boring, so they’re better for control. With these models, the hand is in line with the slot being cut, making it easier to stay steady and bore an accurate slot. There are also many models with top-mounted handles to steady the tool even more.
D-shaped handles are less accurate but more comfortable. The hand’s upright orientation is more natural and easier to push. However, the hand will be higher than the blade, so it’s possible to wobble and make a sloppy cut.
Additional Features
Biscuit joiners may include some additional features that can make storage simpler and cleanup easier.
A sturdy box will keep a biscuit joiner secure when it’s not in use. Many manufacturers package their tools in hard plastic containers that can store a joiner, a few biscuits, and other small items. These cases also make it a cinch to stack tools on a shelf or under a workbench.
As the user bores slots with a biscuit joiner, they can make quite a mess with sawdust and wood chips. The best biscuit joiners come with bags that attach to the exhaust port, catching most of these particles before they hit the ground or air.
Safety Tips for Using a Biscuit Joiner
In general, biscuit joiners are safe power tools—but that could inspire some false confidence. As users become more comfortable using theirs, they might feel they can hold the workpiece with one hand while operating the tool with the other. It’s best to avoid this temptation, as the front lip of the board could lift, potentially causing the blade to strike a hand. Instead, clamp the workpieces to a workbench for a stable base.
Before cutting slots for biscuits, ensure that there are no nails, knots, or other obstructions where the joiner will be cutting. In most cases, the blade will simply cut through these obstructions, dulling the blade a bit. However, there is potential for the biscuit joiner to send a chunk of the obstruction flying with enough speed to cause injury.
Biscuit joiners can produce a lot of dust. While a dust-collection system helps reduce the amount of sawdust, it can’t get it all. Be sure to wear a mask to avoid breathing in airborne dust and safety glasses to keep eyes protected. This safety gear is especially important when working with plywood and medium-density fiberboard (MDF). The glues and chemicals used in their manufacturing can be particularly irritating to lungs and eyes.
- Clamp the workpiece to a bench to avoid potentially striking a hand with the biscuit joiner.
- Ensure the workpiece is free of obstructions like nails and knots before cutting biscuit slots.
- Wear safety glasses and a mask for protection from sawdust.
FAQs
While you may be excited about getting started with a new biscuit joiner, if you still want more info, refer to the answers to these frequently asked questions regarding biscuit joiners and how they work. If you don’t see the required answer here, reach out to the manufacturer’s customer service department and speak with a representative.
Q. What is the difference between a plane, a jointer, and a biscuit joiner?
There are planes, jointers, and biscuit joiners, and they each work differently. A plane is a handheld tool that comes in different sizes and is used for flattening high spots or removing material from a board’s surface. A jointer is typically a floor-mounted power tool (though there are benchtop models as well) that’s used to create a perfectly flat and square board. A biscuit joiner creates slots for biscuits within a joint, producing extra glue surface and perfect orientation for joinery.
Q. What speed should I look for in a biscuit joiner?
To ensure that your biscuit joiner can handle hardwoods, look for one with a 9,000 rpm or higher top speed.
Q. How deep does a biscuit joiner cut?
Most biscuit joiners can cut as deeply as ¾ inch, providing more than enough room for a #20 biscuit.
Q. How many biscuits should I use to join wood?
A good rule of thumb is to use a biscuit every 6 to 12 inches. For weight-bearing projects like shelves and countertops, 6 inches is best to provide support.
Q. What materials can a biscuit joiner work with?
You can use biscuits with a range of wood-based products: hardwoods, softwoods, plywood, MDF, and even laminated particleboard can work with a biscuit joiner.
