How To Cut A Rabbet Joint With A Table Saw

Rabbet joints are a simple way to join two pieces of wood together. They can be cut with a table saw, using a few easy steps. In this blog post, we will show you how to cut a rabbet joint with a table saw. We will also provide tips on how to make the joint stronger and prevent it from coming apart. So, if you want to learn how to make a rabbet joint with a table saw!

Cutting rabbets on the table saw is one of the easiest, but most often overlooked joints to cut. Many woodworkers shy away from using this method because they lack a jointer or don’t have the space for a dedicated outfeed table. The truth is, with two straight boards and a few accessories, you can cut perfect dadoes every time.

1) Prepare Your Stock

The first step is to cut and prepare your stock. If you want a two-sided rabbet meaning it’s visible on both the face frame and the cabinet side then you’ll need to prepare some test pieces.

Start by cutting some scrap stock to size. I used some common pine baseboard, but poplar or any other wood would do just fine. If you want a rabbet that goes all the way through your material, cut your boards about 1/8″ narrower than the final width of your rabbet. A rabbet for face frame applications should be cut 1/4″ smaller than the rabbet’s final width on each board because typically only half of the rabbet will go into the face frame.

Once your boards are sized and ripped down to width, stack three together with their wide sides facing in opposite directions. You can sand or plane the stock if you want, but it isn’t necessary.

2) Mark Your Cuts

To make your rabbet cuts, you need to first layout the cut lines on one edge of your board. To do this, take a sharp pencil or marking knife and place the point where the board’s edge meets the corner of your desired rabbet width. The blade should be perpendicular to that line.

Next, move the blade along the length of that line at least 1″ past either end of your boards. If you have especially longboards, mark both ends so there is no confusion later when setting up for the cut. Remove this excess material with an upward cut from either side of your line or by using a miter gauge to make two angled cuts. Read more here How to cut thin strips on table saw.

3) Setup and Cut the Rabbet

Now that your material is marked and ready, it’s time to set up and cut your dadoes. Place one of your longboards face down on the table saw top with its edge flush against the rip fence. Make sure to leave at least 1-1/2″ between the blade and the outside of the dado stack just in case something goes wrong during setup or while cutting.

Start by adjusting your dado width so that it matches exactly where you taped off earlier. Once you’re satisfied with its location, secure it in place with some masking tape along both sides of the inside channel. Use a scrap board to help push the dado stack snug against the fence and tighten down the tape as needed.

After making this initial adjustment, I like to use a quick-grip clamp across both miter slots to keep everything nice and tight during the cut. If you’re using a shop vac with an adapter, attach it now and position it over your cut line. This not only keeps things cleaner but helps prevent kickback.

Start by taking some light passes at first until you can confirm that your blade height is spot on. Then, make full depth passes all the way through your board until you start seeing some dark smoke coming out of one side of your cut line. After this smoke appears, I usually just take a pass or two straight through the board and then turn off the saw.

4) Remove Your Material

Now that your dado cut is finished, it’s time to clean things up. Begin by pulling out the clamps and gently prying along both sides of your miter slot. You should be able to remove most of the material in one solid piece (see photo). If not, you can use a chisel and some mallet work to hammer it loose.

This will leave you with a few rough edges around the outside that need to be cleaned up. I like to use an oscillating spindle sander, but larger power tools such as a planer or table saw can work as well. If you sand through the blade marks and remove all of the pencil lines, don’t worry; we’ll be able to make those reappear during our assembly process.

5) Cleanup the Inside

After your board has been cut, there will still be some material inside that needs removing. To do this without blowing out your dado, clamp one end of your rabbet boards together with their outside faces flush against each other. Make sure their edges are nice and straight because these cuts need to be square to match up perfectly later.

Take a sharp chisel or marking knife and plunge it down into the middle of the rabbet. Then simply slide it along the entire length of both boards being careful not to shift your cut line. Read more here How to cut 45 degree angle with table saw.

6) Make the Final Cut

Now that you have one board with a completed rabbet, it’s time to make the second cut on the other end (see photo). To do this, just repeat steps 3 through 5 using your first rabbet as a guide. Don’t forget to leave at least 1/16″ between your blade and the bottom of the dado slot during any cuts made! The reason for this is two-fold: 

1) it keeps everything tight.

2) it ensures that you don’t accidentally hit or damage your saw blade.

Once you’re finished, inspect both sides of each rabbet joint closely looking for any gaps between them (see photo). If you find some stray material inside, just use a sharp chisel and mallet to remove it. This is where your blade marks come in handy because they can help determine if there are any irregularities in your joints.

7) Assembly the Frame

Now that both rabbet joints have been completed, it’s time to assemble them together into our frame. I usually go ahead and apply glue on both sides at this point but leave enough room for all four boards to fit back into place later on. For most projects like this, I don’t recommend using screws or nails because they aren’t really necessary with joinery this strong.

Once you’ve ensured that everything has lined up properly, clamp around the entire perimeter of your frame. And remember to double-check all sides before you begin because this is where things can go wrong. If the fit-up wasn’t perfect before, it’ll definitely show here if one or more joints are out of whack.

8) Final Fit & Finish

Before we leave the topic of rabbet joints alone, for now, I’d like to make a few final notes about edge-banding and applying finish to these types of joints. The reason I say this here is because there are some important distinctions between banding the edges of flat panels compared to something rounded like a leg or tabletop tenon.

Tips for getting the perfect rabbet joint every time

  1. Be mindful of blade orientation.
  2. Apply pressure to the dado’s “back” edge as you close it up. This will help prevent any blowout from occurring on the other side.
  3. Keep a chisel handy so you can pry off any material that might have been dislodged during your cuts.
  4. Using a sharp marking knife can be helpful to draw the rabbet joint’s width on your workpiece. This way, you can cut right up against it and have a super smooth joint.
  5. Be sure to leave at least 1/16″ between your blade and the bottom of the dado slot during any cuts made. This is important because it will ensure that everything stays nice and tight after assembly.
  6. If you end up with some gaps, feel free to knock down high spots with a sharp chisel and mallet.
  7. Make sure you double-check all sides before assembly. It’s easy to get lazy with this step but it will pay off later on when your joints line up perfectly.
  8. “Don’t forget your glue!” I can’t stress this point enough because nothing is worse than having one of these boards slip out of place after everything was already fully clamped and there isn’t enough time to fix it.
  9. It’s not necessary, but I like to apply glue on both sides at this point and leave enough room for all four boards to fit back into place later on.


There are many different types of joints that can be created with a table saw, but the rabbet joint is one of the easiest to learn. We hope this guide has helped you understand how to cut a rabbet joint on your own and that it will help take some of the mystery out of woodworking for you.
