Anyone who has ever tried to make a tongue and groove joint knows that it can be a tricky process. If you’re using a table saw, there are a few things you can do to make the process a little bit easier.
In this blog post, we’ll show you how to make tongue and groove joints using your table saw. We’ll also share some tips on how to avoid common mistakes made by beginners.
How to Make Tongue and Groove on a Table Saw Step by Step:
Here are some steps to do this job safely and easily.
Step 1: Rip the boards to the width that you want
Before you start cutting any wood, you need to rip the boards that you will be using for your tongue and groove to the width that you want them to be. For this project, we ripped our boards to 6” wide.
Step 2: Cut the grooves in your boards
Once your boards are ripped to the correct width, it’s time to start cutting the grooves into them. We started by setting our table saw blade to 3/8” width and making a single pass down the length of each board.
Step 3: Cut the tongues on the edges of the boards.
Mark both sides of your board with a square, or ruler that you will use to keep each side flush against the saw blade. This will ensure that you end up with accurate joints.
Step 4: Align your pieces and clamp them down securely
To make sure your boards line up, you may want to clamp the pieces together. When placing the boards side by side, it’s best to have them both facing in the same direction. This means that if one board is not perfectly straight, then its mate may be off just a little bit as well.
Step 5: Cut both tongues on each piece of wood
Make sure your blade is set high enough so it will cut through both pieces without making contact with the saw’s table. By taking this step first, you’ll avoid having to re-cut grooves after you’ve cut all of your tongues.
Step 6: Test fit the joint
Once your tongue and groove are cut, test fit them to make sure they mate together correctly. If it doesn’t fit perfectly, adjust either your fence or miter gauge depending on whether you’re cutting grooves or tongues respectively. Keep testing until you get a perfect fit – once everything lines up perfectly, go ahead and mark your cut lines on the board.
Step 7: Cut the boards to their finished lengths
You’ll need to be extra careful when making this cut, so take your time. Start by making a pencil line about halfway up along one face of the board. Then turn it over and draw another line directly across from the first one. Now you can safely use these lines to guide your saw without compromising either piece of wood with the blade itself.
Step 8: Assembling the pieces with glue
To make sure the joint is stable, include some glue in your tongue and groove joints. Using a small brush or toothpick, apply glue to both surfaces then insert them together. Allow the pieces to dry overnight before you handle them again.
You’re done!

Mistakes that beginners make when cutting tongue & groove joints?
The number one mistake that beginners make is cutting tongues instead of grooves – or vice versa! It’s an easy mistake to make because both cuts look similar on paper, but in life, they are very different.
Tip: Always double-check your measurements before making each cut – if you have a tape measure, take the extra time to ensure that everything is lined up correctly.
Troubleshooting tips
The biggest problem beginners face when cutting tongue and grooves is a misaligned joint. If the pieces don’t fit together well it can be challenging to get a tight-looking joint. Here are some steps that might help:
Pressure down on the head of the saw with one hand while you slowly push through the cut with your other hand. This will keep things nice and steady for an accurate cut.
Depth matters! Make sure your blade is set high enough so it will cut through both pieces without making contact with the saw’s table. By taking this step first, you’ll avoid having to re-cut grooves after you’ve cut all of your tongues.
Test fit the joint after each cut until it fits right. If it doesn’t fit perfectly, adjust either your fence or miter gauge depending on whether you’re cutting grooves or tongues respectively. Keep testing until you get a perfect fit – once everything lines up perfectly, go ahead and mark your cut lines on the board.
Safety Tips
If you’re cutting a board longer than 36″, make sure to use an auxiliary fence because the stock fence is designed for shorter pieces.
Don’t forget your push stick! Always use a push stick when ripping any kind of board on the table saw. It helps keep your hands out of harm’s way and prevents kickback.
Conclusion
So there you have it – your complete guide on how to make tongue and groove cuts on a table saw. As with any woodworking project, practice makes perfect, so be sure to get plenty of hands-on experience before tackling a bigger project. With a bit of practice, you’ll be able to create beautiful tongue and groove joints that will last for years. Thanks for reading!
FAQ’s
What do “tongue” and “groove” mean?
The “tongue” is a protrusion on one of the pieces, and it slides into a groove on the other piece. The tongue and grooves fit together tightly. Most tongue and groove joints have a 1:6 or 1:8 slope so that they lock together properly. If you use boards with a different slope, they may not fit together as well.
What is a “stopped” tongue?
A stopped tongue is also called a blind groove or rabbet. This type of joint doesn’t go all the way through one of the pieces. For example: when building cabinet doors with 1/2 inch plywood and 3/4 inch pine, you might make a stopped groove on the bottom of the plywood. The tongue would fit in all the way but it wouldn’t go through to the other side.
What are some benefits of using a table saw?
A table saw makes cutting grooves and tongues very easy because it has fence guides that help you set up.
What tool is used to make tongue-and-groove?
There are a few different tools that can cut grooves or tongues. The most common is a table saw with an appropriate blade specifically designed for cutting grooves and tongues, but you could also use a router, jointer, shaper, tenon cutter, and dado blades on a table saw, or even a chisel to make the joint by hand.
What router bit do you use for tongue-and-groove?
There are several common router bits used to cut grooves and tongues. The most popular bit is called a ‘dado blade.’ It cuts grooves larger than 1/4 inch. If you need smaller grooves, there are specific bits with the names in their product descriptions that work well for tongue-and-groove joints.
