Can I Use a Dado Blade on a DEWALT Table Saw?

Watch the user manual first and know whether it allows a dado blade or not. The models named DEWALT DWE7402DI, DWE7491RS allows a stack of dado blades or dado sets. So, these table saws can make the fastest dado cuts.

On the other hand, table saws like DEWALT DW745 don’t accept a single or a stack of dado blade sets. The main reason is, it can’t ensure enough space for a single dado or a stack of dados. They bear nearly dado blades of 10-inch. In some cases, the shaft of the saw is not too long to accommodate a dado blade. 

However, we see many of the DEWALT table saws that accept a full set of dado blades, but they take a single piece of the dado. Mainly, they don’t have enough thread, they can’t safely thread the nut onto the arbor.

Can DEWALT DWE7480 Use Dado Blades?

No, its drive system is not built to take a heavy dado set on it. The other portable table saws of DEWALT support dado-type blades because they have their back nuts and flange separated. So, at the back flange’s place, keep the front washer, then set the dado. But for the DEWALT DWE7480, the nut and flange are combined, not separated. 

For this, no way to use 13/16” dados. But according to the manufacturers, 3/8” dados can go easily with this DEWALT DWE7480.

Can I Use an 8 Dado Blade on a 10 Table Saw?

The answer is “Yes”. If both the arbor hole diameter on the dado set and the arbor diameter on the table saw match together and the arbor is suitable for the dado, you can easily put an 8-inch dado on a 10-inch saw. 

So, there Should not be any problem using a dado blade of 8 inches on a table saw of 10-inch. Many of the woodworkers use dadoes this way. And it is very common.

Benefits of Using an 8-Inch Dado on a 10-Inch Table Saw

Low Force Needed

If you keep the dado blade smaller than the table saw, this blade with a smaller diameter will help the saw to give more force on its teeth than any of the blades with a larger diameter.

Can Cut Most of the Dadoes

No one uses dado blades to cut deeper than nearly .5 to 1 inch. A dado blade of 8-inch surely cuts that margin and will be enough for cutting most of the dadoes.

Lightweight

Because of having a dado blade with 8-inch diameter, the blade will be lightweight. And so, less effort will be needed to cut a wide and deep dado. 

Cheaper

Less steel is needed to build an 8-inch dado rather than a 10-inch dado. But their dado cuts are almost the same in size. So, we can tell that a dado blade of 8-inch diameter will be a cheaper choice for you.

How to Install a Dado Blade on a DEWALT Table Saw

Now I am going to show how to set a dado blade on a DEWALT table saw. Setting up a dado stack on a table saw may be tricky. But follow these instructions step by step. These will help you to make this process easier.

Check Out the Dadoes

There are two dado blades in the set. All the teeth of a dado are used to cut on one side. Make sure that the right-sided plate is sitting on the right side of the stack. And the left one is on the left side of the stack.

Check the Chippers & Shimmers Also

If you need wider cuts, use the chippers. A chipper has four teeth. But there are chippers with two teeth also. Chipper’s teeth are wider than its body. Suppose, a chipper of 1/8-inch body contains teeth nearly 5/32-inch wide. This mechanism is to eliminate all materials from the bottom of the cut. 

Now come to the shimmers. They sit between the chippers and blade plates.

Check the Height of the Stack

Put the right plate on a table, then stack your chippers, then put the last plate. Don’t forget to set the shims between the chipper and top plate. Now you have to check its height. Take a little wood piece, and find how depth the stack can cut.

Place the Stack on Arbor

If the stack can cut the depth you need, then place them on the arbor in the same sequence. The shims of the stack must be thinner than the machine threads. Otherwise, your shims may be damaged.

Tighten the Stack

After putting it all in place, make sure that the all-chipper teeth stay in between the plate teeth gaps and shims are tight in their places. Then install the arbor washer, tighten the nut. Tighten it as you do with the normal blades. 

Other Steps

Set the depth of the cut. Then run a test cut. Try to make an extra small gap for applying the glue.
