Best Biscuit Joiner for a Woodworker
Festool Domino Joiner
While not technically a biscuit joiner, the Festool domino joiner produces similar joinery, but instead of traditional biscuits, it uses rectangular-shaped tenons called dominos for rock-solid joinery. You have to have it hooked up to dust collection, as it creates so much dust and a dust clog can mean a broken bit. This means adding an adapter to your shop vacuum or investing in the Festool CT26E dust collector, which integrates with the domino and other Festool products.
When Festool released its domino tool in 2007, it was a game changer. It’s a floating tenon system with a high degree of accuracy and added strength. The tool has five mortising depths, an adjustable mortise width and a pivoting fence for angled mortises. Instead of a circular blade, this handheld, horizontal oscillating router has a spiral cutter to bore the mortises.
“The tenon, or domino, is made from solid birch, sipo, or metal allowing for use in interior, exterior and breakdown furniture applications,” explains Tom Noffsinger, a veteran woodworker for over 25 years. He chose the Festool for quick and precise work flow, moving from varied joints and wood species smoothly and with speed.
Logan Newman, owner of Newman Woodworking, uses this model for mortise and floating tenons, but also to create expansion slots in his custom furniture to allow wood movement. “The domino performs multiple jobs more efficiently and cost effectively than any other tool in the shop,” he explains. “If you’re a professional cabinetmaker or just a weekend warrior hoping to produce beautiful furniture, faster, the Festool is a standout option.”
What’s included: You’ll get the Festool domino joiner, cross stop, open-ended spanner (WAF 8), trim stop, 5-millimeter cutter and storage container.
Pros
- Stronger than doweling or biscuits
- More than twice as much gluing surface as biscuits
- Enhances speed in production
- Comes with a three-year warranty
Cons
What to Look for When Buying a Biscuit Joiner
Before making your final biscuit joiner selection, keep these considerations in mind:
- Cost: Biscuit joiners vary greatly in cost. “Entry-level biscuit joiners can start around $50 to the very high-end Lamello models that can top $700, so be sure to fit the tool to your needs,” suggests Listi.
- Power and speed: Ideally, look for a model with 6 to 8.5 amps, and 8,000 and 10,000 revolutions per minute (RPMs).
- Dust collection: Joiners have a small port that sends wood chips to a cloth bag. This works well for about a dozen biscuits, then the port tends to clog. You’ll want a dust collection system for bigger jobs and a joiner that can attach to a shop vacuum (you may need to add an adapter).
- Handle styles: You can choose between a barrel grip, where you’re actually grabbing the body of the machine, or a D-handle style, which is more comfortable, but less accurate.
- Fence features: Joiners have a fence that can be set up to 90 degrees, but you may want to use a joiner that can be set up to 135-degree angles. This allows you to set the joiner on the inside or outside face of a mitered joint. The fence should track up and down while allowing the fence to remain parallel to the blade. Look for a rack-and-pinion mechanism for adjusting the fence.
- Blade options: The 4-inch diameter blade is standard on most biscuit joiners, and is great for the common #0, #10 and #20 biscuits. But if you want to use your biscuit joiner for face frames, you’ll need a 2-inch blade and smaller biscuits. Not all biscuit joiners can fit the smaller blade, because the plunge mechanism has to be compatible with the smaller blade. If you find yourself using smaller biscuits for face frames, make sure your joiner can be retrofitted for this purpose.
- Additional features: Biscuit joiners may include some additional features, like hard carrying cases for easy storage when not in use. Many manufacturers included standard biscuit sizes so you have everything you need to get started.
Why You Should Trust Us
As an award-winning woodworker, I have experience with woodworking, DIY and home improvement. I’m also the owner of a one-woman woodworking studio where I make wooden educational toys and furniture using advanced joinery techniques. For this article, I also enlisted Sarah Listi, owner of Tool Girl’s Garage, a blog and social media presence dedicated to tool reviews, woodworking, renovation and construction. Listi is co-host of the Murder House Flip TV show on the Roku Channel.
Additionally, I consulted with two experienced woodworkers and furniture makers, Tom Noffsinger, a veteran woodworker for over 25 years who has attended Festool training as a serious hobbyist, and Logan Newman, owner of Newman Specials Woodwork and creator of jigs and tools for WeCNCthat store.
How We Found the Best Biscuit Joiners
In 1968, Lamello released the first biscuit joiner and, since then, this tool has been used in woodworking and home projects to offer quick, precise and strong joints. Selecting the best biscuit joiners to test depended on power output, accuracy, ease of use, reputable brands and customer reviews. Our top picks have powerful motors of 6 to 8.5 amps and from 10,000 to 12,000 RPMs. Feature must-haves include adjustable angles and cutting depths, 0- to 90-degree angles and dust collection. Taking all of that into consideration, I was able to dwindle the list down to the very best top five biscuit joiners.
FAQ
What does a biscuit joiner do?
A biscuit joiner is used to join two pieces of wood together using concealed joints. The joiner leaves an arched slots into the mating edges of the wooden pieces that takes compressed wood biscuits. When glue makes contact with the compressed wood, the biscuit expands to make a tight joint, perfect for manufactured material like medium-density fiberboard (MDF) and plywood.
The biscuit joiner can do many different joints, like edge-to-edge joints, splines on mitered boxes and biscuit cutting slots for table clips. Miter joints are another ideal place for biscuits. Using a biscuit joiner on mitered parts is a smart way to add strength to the joint and prevent the two halves from slipping as you apply clamp pressure. I particularly like biscuits for attaching face frames to plywood cabinets without pesky holes that require patching. I don’t like to use hardware in my projects, only wood joints. So when I want to do a panel glue-up, I use the biscuit joiner for alignment. The biscuit joint is used for its accuracy and speed while being quick to learn.
Is a biscuit joint the same as domino joint?
Biscuit joints and domino joints are similar in that they are seamless, concealed joints used to connect two pieces of wood together. However, they differ in the method and type of joinery they provide.
Biscuit joinery involves using curved wooden biscuits made from compressed wood, typically beech. They provide alignment assistance and some added strength to the joint, but they’re not as strong as other joinery methods, like mortise and tenon.
Domino joinery uses a floating tenon system. A handheld, oscillating router with spiral cutter creates the corresponding holes. Instead of inserting biscuits, it uses pre-made, elongated loose tenons called dominos, which are fitted into the mortise. The machine cuts mortises and the dominos act as floating tenons. Domino joints offer superior strength compared to biscuit joints, due to the larger and more substantial surface area for glue adhesion and the mechanical interlock between the tenon and mortise.
While both techniques assist in aligning pieces and strengthening joints, Domino joinery generally offers more strength compared to biscuit joints.
