Overview

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.

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??
Gary M on Sep 19, 2016
BEST ANSWER: 29/32"

Nice unit, better service!
Got this set-up to begin a cabinet project I've been planning for a while. For the most part it performs as advertised: clean smooth cuts, flat bottoms. Unfortunately, I found my 1/16th chipper had a long tooth which would groove the bottom wherever it was placed. Fortunately, Rockler and Freud stand behind their products and they sent a replacement with free return without a moments hesitation. Very, very reassuring customer support.

Best dado set I've used
This is my second dado set. The first lasted over 15 years in my commercial cabinet shop. It leaves a superior flat bottom, chip free cut. The set comes with several shims to fine tune the width and accommodate today's undersized panels. The 8" set requires more horse power when stacked 3/4" +.

Great customer service
I received my first set of dado blades and it had two right hand outside blades and a damaged case. I think Freud packaged it incorrectly. I called Rockler customer service and they sent out another set immediately, without question and pre-paid return postage. The replacement set works great. The 3/32 inch blade is terrific and is great when working with plywood. The dado fits perfectly. I had some hesitation when purchasing this set. The mass of the chipper blades takes a long time stop spinning but so far it has not been an issue.

Excellent Dado Set - who cares about the case?
I use this dado set on a regular basis, primarily in cherry, maple, oak, and a variety of plywood types; and I think this set is excellent. I never have tear-out and it leaves a very clean edge all around. Yes, the case is cheap, but it works long enough to build your own case for saw blades. Besides, judging the case is like complaining about a table saw because you don't like the color of the paint, it will never impact your project one bit!

cuts like butter
i used this set to make 3/4 wide x 5/8 deep dados in oak... i thought i would need to make 2 passes because of the width and depth... made a trial cut and it was so smooth and easy i went for 1 pass... made 128' of dados with no issues... great product.

Great blades, packaging a disaster
I have found these blades to be everything the others say about them - clean edges, flat bottoms (at least for the chippers I have used so far). My only issue is the packaging. The interior packaging was broken when I received the package. Blades and chippers were sliding around in the case, obviously baking against each other. The plastic forms holding the blades are in no way sufficient for the weight of the blades. It is unacceptable for a nearly $200 set of blades to be packaged so poorly. I will have build or buy something to store these blades because this plastic case will not provide enough protection.

These work great and are well balanced.
With both the cutter and chipper blades this blade can remove lots of material quickly with nice smooth cuts. Stacked dado always has more setup time, but worth the effort. Nice storage box to hold all of the parts and pieces. This is one product where you get what you pay for. My 1st project using this was doing over 1000 cross cuts in making some dentil molding and never had an issue. Make sure it is used with a good table insert for the blad that will fit tight by the blade. This is being used on a Saw Stop with the proper blade stop cartridge.
