good but not perfect
This is my first stacked dado blade so am not sure if this is common. It cuts very smooth flat bottom dados and comes in a great organized case. The only thing is one of the two outer blades cuts slightly deeper than all the others. less than 1/64 so the bottoms of the grooves aren't perfect, but very close. I am not sure if this is to be expected or a fault with this blade.

Very Good
I'm a retired builder/carpenter who now spends some of my free time building/making things that I want. Pay sux but.... LOL
This is my 1st experience with a dado stack as I've always used a router table for making dados. I plan to use it to make box joints for little "treasure chests" for my three grand daughters. The case the dado comes in is plenty sturdy and will be great for off duty storage. My 1st use was making 3/8 in. finger/box joints...test pieces came out a little loose, but that's not the fault of the dado stack. I just need to tighten up my jig placement a tiny bit. The cuts themselves come out as true as can be and with flat and smooth bottoms. And no tear out on the 1/2 inch Ash I was using. I mic'd the width of the stack and it comes out extremely close to 3/8 in. Width in MM is 9.523, which is damn close to perfect. There are less expensive dado stacks, and more expensive ones as well. But considering the performance of this stack, I see no sense in spending hundreds more, just not worth it.

True 8 inch dado...
...which is important on my Sawstop. I originally had a Freud Super Dado which is really 8 1/8 inches. It required me to bottom out the brake cartridge and it still didn't meet the recommended clearance. This Dewalt doesn't present this problem. I was also pleasantly surprised with the cut quality - every bit as good as the Freud. Very happy with this dado set!

Smooth flat bottom dados and rabbets. Very happy.
Had this set for a few years now. Im very happy with it. Flat bottom dados and rabbet cuts on my table saw. Very nice case for the blades too. The chippers are 4 pointed and space evenly with ease. My only complaint is the way the case is designed the manual didnt fit in very well. I have since lost it and can't find one online. Not enough to lose a star though. Im very happy with this set.

I had a Freud 208 , was ok but this thing rocks
No Bat Wings
No splinter out even on chineese ply (Zero clearance insert)
Only very fine lines on bottom.
Carbide looks fairly decent,
will see how it holds up.
For the price Ill keep it

I'm happy
I used the set to cut a number of dado's and rabbets in birch plywood. Nearly zero tearout or chipping. It actually performed better than the blade I used to cut the sheets down. Of course it was new out of the box, so I hope it keeps cutting well after a few hundred cuts. Much cheaper than the competition, so I am satisfied.

will it fit 10" table saw?
A shopper on Jan 13, 2018
BEST ANSWER: Yes it will fit your 10” Dewalt table saw but the Dewalt insert cover isn’t the right one for the dado head. I had to make my own out of 1/2” plywood.
How wide of cut will this dado set make
Woody on May 15, 2015
BEST ANSWER: The chipper blades and shims give you any width from 1/8th inch to 13/16ths.
How wide is 093 ?
Evan D on Mar 10, 2020
BEST ANSWER: 15/16 inch
Will the dado set fit the dwe74911 if it will do I need to buy a throat plate for the dado set?
A shopper on Jul 8, 2018
BEST ANSWER: I don’t believe that it fits. I suggest you contact desalt to verify. I recall that dados only fit a few models. And you will need a new dado specific plate if the auger can handle the dado thickness.
Hi, Will this set of dado blades work with a DWE7480? and do I need to use a new throat plate? If I need a new plate, what model should I buy? Thanks!
Peter on Dec 18, 2014
BEST ANSWER: Yes, this dado set will work for the DeWalt Table Saw. You do not need to use a different throat plate.
Will this set work on a DW744 table saw?
