Hey guys and gals. I’m looking to grab a dado blade for my Delta 10” table saw.

My goal is to start doing box joints. I’m going to build a jig (well, hopefully) so that I can get even cuts and hopefully make my work go faster.

Any suggestions on something that isn’t going to break the bank but will still do the job? Is the standard size 1/2” or are these blades adjustable?

Thanks.

I use this one as my main dado set, and for box joints too.
Pretty much flat bottoms. Great case, love it.

The entry level Freud 8” dado set works great. I have built dozens and dozens of large projects with it, and it has never needed sharpening. It still cuts clean and smooth tenons and dados.

One way to save money without sacrificing quality is to go with a 6” set instead of 8”.
6” blades will still cut 1-1/2” deep typically, and that is as deep as I have ever needed.
8” sets will cut one inch deeper, but usually sell for twice the price.

I have an 8” set and regret ever buying it. I would rather have a 1/4” kerf box joint blade and a 6” dado set.

The DeWalt/Delta 7670 set is the best bang for the buck that I know of at ~ $100. The Infinity Dadonator is the best overall set I know of starting @ ~ $180 for the Dadonator Jr.

Wow guys, thanks so much for this information.

@ crank49: Even though I have a 10” saw, the 6” should work?

Thanks again!

Yes, the 6” set will work on your 10” saw as long as you have a 5/8” arbor. Save your money and get the 6” set.
If you’re making box joints, you’ll never use the capacity of the 8” set , which is about 2 1/2” deep.
Don’t forget to make yourself an insert to accommodate the width of your dado : )

It’s worth noting that 6” sets aren’t always cheaper than 8” sets….sometimes the 8” sets go on sale for less than the 6”, plus not all manufacturers offer a 6” set. Don’t go out of your way to get a 6” set if an 8” is the best performer for the money.

Also worth noting, if you ever get an incra ibox (amazing jig!), the 6” dado set limits the thickness of box sides you can use. I can’t remember the exact numbers, but I know it won’t cut joints in 3/4” pieces.

6” over 8”? I kinda think that’s false economy. An 8” dado will give you a faster rim speed, a better angle of attack, and will cut cleaner and last longer between sharpenings (more teeth to share the load). If I could swing a 12” set I would.
A dado set is useful for much more than shallow grooves. Sometimes you will want to go in high or very deep or even use it in conjunction with a sled (which will cost you depth). Buy the largest and best that you can afford; it’s a lifetime quality purchase for any hobbyist.

The Freud 8” adjustable is the best bet in the long run. Being Freud it is of course a high quality tool and has a unique and invaluable “dial a width system”. Its worth every penny to NEVER deal with shimming again. I could never go back.
