SD508 Freud Dado Set

Item #
100% 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.

  • Cuts chip-free dadoes, slots, grooves and rabbets
  • 3/32" chipper (included) for undersized plywood
  • Shim set is included for fine adjustments
  • Cuts plywood & laminate to solid hard and soft woods
  • 3/32" chipper allows cut width to be adjusted in 1/32" increments

Woodworking Experience:
Dado boades
Blades and chipoers very sharp and travels smoothly through the cut. I made a long tenon in Baltic birch which is hard. I was surprised to see the lateral cuts were not exactly level with each other. I don’t know why this would be unless the blades are slightly different diameters. But they are so well balanced that the is no no load vibration. Good product

Woodworking Experience:
Easy, Accurate Dados
Freud's SD508 super dado set was a pleasure to use, easy set up and yielded accurate cuts.

I chose this set for making 1-1/2" D x 3-1/2"W dados in red oak legs for a new work bench. First I mic'd the width of several teeth on each blade and chipper to confirm their individual widths--these were accurate to + .001". Next I made a 1/2" stack (without shims) and measured the overall width--total width was slightly over .500" but I was making several passes (width & depth) so this was insignificant. On measuring blade height (protrusion) through the table saw top I noticed one of the outside blade teeth was .003" taller than the rest; I set the height to match the tallest tooth and went to work, slowly making passes. The side wall cut was extremely smooth with no burns or chatter marks; the bottom of the cut was relatively smooth, however, there was a noticeable, but very fine, groove at the bottom of each through pass that marked the location of the highest tooth. This was easily remedied with light sanding. There was occasional fuzziness on the end edge of cuts when I traveled too fast. I detected no vibration in the stack while making numerous passes.

I am very pleased with the results and would highly recommend the Freud SD508 Super Dado set.

Does an excellent job.
I had been using a router to cut a rabbeted or lap joint in 1" pine for bee hives. I bought the Freud dado set thinking that it might be easier and faster. The dado set makes a clean side and bottom that works perfect. Much faster and easier. Well worth the money.

High Quality Dado Set
Great dado set. Extremely sharp and cuts true and smooth flat bottomed dados. The stacked dado set comes with plenty of chippers of different thicknesses and shims to adjust the width of cut.

The set comes with a DVD with instructions on how to operate the adjustable dado and tips on how to make a sled. It does not, however, provide instructions on how to operate the stacked dado but it was easy enough to figure out. It does come with a very handy chart explaining which combination of cutters and chippers to use to achieve different dado widths. Very helpful!

Would definitely recommend this high quality dado for the discerning craftsman.

Does this work with a DeWalt DE745 portable saw?
Paul A on Apr 12, 2016
BEST ANSWER: Sorry, I do not know if it will work with your saw. however, it only works partially with my table saw because the arbor is not long enough on my saw, I can only get a few of the blades on and still get the washer and nut on the arbor to hold the blades so I can only cut about 1/2" dado. Make sure your arbor is the right length and thickness for the hole in these blades.
What is the max dado width for this dado set it appears to be 5/8 inch??
