SD506 Freud Dado Set

Item #
90% of 100

The SD500 Series of dado sets cuts everything from veneered plywoods and laminates to solid wood, chip and splinter-free with a super smooth, flat bottom. The SD500 Series dado sets were the first to include a 3/32" thick chipper and has the flexibility of an adjustable dado to handle today's undersized plywood. This allows the cut width to be adjusted in 1/32" increments and doubles the number of slot widths available. A shim set is also included with the dado set for fine adjustments. Use on all table saws, and radial arm saws for cutting slots, grooves, dadoes, and rabbets in softwood or hardwood.

  • Cut chip-free dadoes, slots, grooves and rabbets
  • Shim set is included for fine adjustments
  • Cuts plywood & laminate to solid hard and soft woods
(4) 1/8" Chippers
(1) 3/32" Chipper
(1) 1/16" Chipper
(1) Plastic case

Clean Dado's
Marketing hype sell a lot of mostly useless things. So I really don't pay much attention to the hype. I do trust those who have used the product and share their experience. That's why I chose the Freud SD500 Dado Set. As a beginner in woodworking I like items that are easy to use and adjust. The SD500 couldn't be easier - just follow the included directions. The provided shims make getting the right width dado very easy. And the hype was really true in my case - clean, splinter-free dados that do have remarkably flat bottoms. For a beginner this was a perfect choice.

Still going strong
I purchased a Freud dado set that came in the red case where they attach to the side with a screw in attachment for 9 yrs now and after many uses it still is razor sharp and cuts excellent.

I was using a cheap $50...
I was using a cheap $50 dado set from a big-box store and it was chipping the heck out of my birch plywood and left a horribly messy bottom. I took the plunge on this Freud set and it was money well spent. No chipping at all and the bottoms on my dados are clean.

I am very satisfied with this...
I am very satisfied with this set. It makes smooth cuts, is easy to tweak and adjust and looks like it has enough carbide on it to last a lifetime of sharpening! In my opinion, the 4-tooth chippers make a big difference. I very briefly used the Dial-a-Width set in the psat and was not happy with the way it fit on my arbor (was difficult to slide on / off and tighten or loosen due to the large hubs). Incidentally, I saw no visual difference in cut quality between the Super Dado and the Dial-a-Width Dado. My only gripe is the case. I would have gladly paid an additional $10-$20 if Freud would have provided a hard plastic insert with padding between the blades. I will likely make something to accomplish this. If you want a solid set, go with this one. The 4 chippers is worth the upgrade from Freud's lower end model and the adjustability of this one is just right for me.

Have used my dado set only...
Have used my dado set only for a few things around the garage but am impressed up to this point. VERY clean dado's without chipping/splintering even in plywood. I have always used my router table for dados, but am slowly gravitating back to the table saw and my new dado blade because the cuts are so clean.For the extra $ why not buy the 8" set. So far I love the dado set.

I have had my Freud Super...
I have had my Freud Super Dado 8" set for at least 4 years now, and it is still going strong. I have used it on solid Oak and on plywood, and for both, there is always a clean cut, the bottom of the dado is smooth and square, and I am very pleased with the results. The plywood will normally fit in the dado perfectly when I use the 3/32" chipper blade with 3 of 1/8" chippers (and the two 1/8" outside blades)but I sometimes need to add in a shim (included) for just the right fit. My only regret is that my Delta X5 contractor saw's arbor is not long enough for me to try more than a 3/4" stack up. However, it cuts those dados without bogging down at all. (My old Craftsman table saw was just minimal for cutting a 3/4" dado 1/2" deep, but it had issues ripping at times too.) Just make sure you use a zero clearance insert for the blades.If you are trying to decide between the 6" or the 8", I would not hesitate to spend the extra $20 to go for the 8" blades.Keep the sawdust flying. I would not hesitate

Terrible surface quality
I finally had the opportunity to install my 6" dado set and use it. The shoulders are perfect. the bottom of the dado looks like I used a hatchet to cut the dado. The uneven surface shows up in the side view when mating part is installed. I have to cut the dado short of finish depth and hand work to finish depth to get an acceptable dado. I've read other unsatisfactory reviews regarding this problem but ordered figuring it must be rare. Rare or not, i have the issue. I should have spent more and got a better quality tool.

Because of the ratings and reviews and because you had a 20% off one item coupon. I felt that I would never be able to buy them for less.

Can I use this on my Skilsaw worm drive 10”table saw?
Bill M on Nov 20, 2019
BEST ANSWER: Hello Bill,
My saw is a Shopfox 10" table saw, belt driven with 5/8" arbor. If your asking will a 6" dado set work on a 10" table saw my answer would be yes. I think the most important question you want to ask yourself is how high does your 10" blade rise above the cutting surface. Since this is only a 6" blade you'll be losing 2" of cutting height which will limit how deep of a dado cut you can make. If you think your future dado cuts will be deeper than this set can make, you may want to opt for the 8" dado set.
