Understanding the Dado Cut

Definition of a Dado Cut

A dado cut, a form of woodworking joint, entails cutting a trench or channel into a board to form a groove. This groove is then used to join two timber pieces in order to generate an unshakeable and secure bond. The measurement of the depth and width of the dado cut differs based on the thickness of the wood, the particular task, and the type of joint being forged.

Types of Dado Cuts

There are several types of dado cuts, including:

• Through dado: A through dado extends completely through the width of the board, creating an opening that allows the adjacent piece of wood to be inserted.
• Stopped dado: A stopped dado is a dado that ends before reaching the edge of the wood, creating a groove that does not extend to the end of the piece.
• Rabbet: A rabbet is actually a dado that is made on the side of a panel. To know more about the differences, check out my article Rabbet Vs Dado Vs Groove (What’s What & How to Make Them). Just like a dado, you can make a rabbet cut with miter saws.

The Importance of Accuracy When Making a Dado Cut With a miter Saw

The precision of the dado cut is vitally important in guaranteeing the firmness and steadiness of the finished joint. If the cut is not properly done, it can lead to a poor fit between pieces of timber, producing a feeble or unsteady joint.

Furthermore, an inexact dado cut can spoil the look of the final product, hence it is essential to devote due attention and care to make sure that it is correctly made.

Why is a Miter Saw a Good Tool for Making a Dado Cut?

The miter saw is a hugely beneficial tool for carpentry and woodworking, offering unparalleled accuracy in its cuttings. It can create dado cuts to a very exacting standard, and with the added ability to tilt and rotate, angled cuts become much more straightforward.

However, there is a small caveat. For cutting dados with a miter saw it must be equipped with a depth stop. Not every miter saw has this. My older and cheaper saw didn’t have this, but my newer Festool Kapex120 has it. If you’re looking for a new miter saw, this is in addition to the tips you can find in my article What Miter Saw Do I Need? 11 Tips to Find the Best Miter Saw is one of the features to look forward to.
To read my honest thoughts about the miter saw I have in my workshop, check out my in depth review article Festool Kapex KS 120 REB Review: Is This the Best Miter Saw Ever?

If you already have a saw that doesn’t have this feature, you can always make a DIY miter saw depth stop by placing a block between the moving parts of the saw.

Can You use Dado Blades on a Miter Saw?

As far as I know, it is not possible to place dado stack blades on sliding miter saws. I strongly advise against trying this, as it can be risky. Extra saw blades may hit the blade guard, posing a hazard to the operator. To keep safe, it’s wiser to stick with the original blade for cutting on a sliding miter saw and follow the methods mentioned in this article.

Preparing Your Miter Saw for a Dado Cut

When performing a dado cut with a miter saw, it is imperative to select the correct blade type. To find the right blade for your saw, I earlier wrote this guide.

Installing the blade on a compound miter saw is easy, but it needs to be done carefully as instructions must be followed precisely in order to protect both yourself and the saw from harm. Here are some basic steps for achieving this:

1. Unplug the saw from the power source.
2. Remove the blade guard and blade washer from the arbor.
3. Place the blade onto the arbor with the teeth facing in the correct direction.
4. Replace the blade washer and tighten the arbor nut to secure the blade.
5. Lower the blade guard.

When changing the blade on a miter saw, it is essential to take necessary safety measures. Disconnect the power source and don protective gloves, eye gear, and follow guideline instructions for proper installation. This helps safeguard against sharp incisions and debris that may be tossed in your direction.

How to Make a Dado Cut with a Miter Saw

Step#1: Measuring and Marking the Wood For the Cut

To ensure the accuracy of the miter saw dado cut, it is essential to measure and mark the wood before cutting dados with a miter saw. Begin by taking the width and depth measurements and indicating these on the material. Then, take a square and draw a line along the length of the piece, specifying where the cut should be made.

Step#2: Adjusting the Miter Saw for the Depth of the Cut

Before executing the cut, it is essential to configure the miter saw for the correct depth. The depth for cutting dados with a miter saw will be contingent on the thickness of the timber and what type of joinery is being implemented.

To modify the depth of the cut, unfasten the locking knob and regulate the height of the blade until it reaches your desired measurement. Subsequently, fasten the locking knob securely to affix the blade into place.

Step#3: Making the Cut

Once the miter saw is ready and your lines are marked, clamp the lumber in position to ensure it won’t move whilst cutting dados with a miter saw. Then, power on the saw and gradually guide it along the marked line. Move with caution to guarantee that the cut is precise and consistent.

Repeat this step on the other side of the dado and afterward you can remove the rest of the material by making several cust one next to the other until all the material is gone and you have a perfectly made dado.

Step#4: Cleaning Up the Edges of the Cut

Once the cut has been made, use a chisel or sandpaper to refine the edges of the dado cut. Careful attention should be paid to avoid over-sanding, as this can diminish the strength of the joint. Once the edges are smoothed out, check that the cut is sized and shaped accordingly by testing how well it fits together.

Alternative Methods for Making a Dado Cut

Using a Table Saw With Dado Blades

A table saw is another popular tool employed to produce dado cuts. This process demands that the height of the blade be adjusted to the required depth and then the rip fence is used to slide the timber along the cutting line. Compared to a miter saw, it is more exact and useful for cutting longer lengths. Nonetheless, it carries an increased risk as the cutting edge is exposed and wood passes quickly through the saw.

On a table saw you can use dado blades. However, in some countries, it is illegal to use them. Check out my article Can I Use Dado Blades On My Table Saw? Solved! to see if a dado blade for table saws is allowed to use in your area.

Using a Router

A router is an optimal choice for creating aesthetically pleasing or intricate dadoes. You can employ a straight bit for the typical cut or a dado bit for wider, more intricate cuts. To make the cut, simply adjust the router bit to the appropriate depth, firmly secure your piece of wood in place and steadily guide your router following your marked line.
