I have just recently purchased a radial arm saw and will be using it as a dedicated dado cutter. Can anyone recommend a good dado set for the radial arm saw. I have heard that it is highly recommended that the blade have a 0 or -5 hook to prevent the blades from climbing into the material. Keeping this in mind, I would appreciate any suggestions anyone may have. I would also like to keep this dado set purchase as economical as possible as I am just not able to drop $250 on a dado set right at the moment. Thanks in advance for any advice you can lend me.

We are looking at adding a dado set to our RAS we just added to the shop. I will be on the lookout for a good set. I know MLCS has some good product and I like the looks of their dado set but I did not see anything specific to degree of hook or if it was good for a RAS. Woodworker Supply has a good set that is stated for use with a RAS but they want around 170.00 or so for it. I do think a little extra to ensure safety is good. I do think the MLCS dado is probably sufficient but we intend on using out set up often.

i bought a set from delta 14 years ago..and there still working great today…but there are a few good ones out there…i recommend something with the chippers in it…dont go with a dial up one…i think your better off with ones with chippers…if you can make sure you get one that gives you a flat bottom…some will give you a concave bottom…and you dont want that as sometimes your datto is exposed…and get one that is carbide tipped..i hope this helps somewhat…good luck and enjoy it when you do get it…..

The MLCS set is a replica of the Systimatic 42T Superfine set, also similar to the Oshlun set, Grizzly set, and a few other clones. These all have a fairly steep hook angle as dado sets go (prolly + 15-20°)...fine for TS, but not ideal for RAS. Note that some of these clones use C4 carbide (Oshlun/MLCS), others C2 (HF), and soem C3. Also note the hook heavy positive hook:


The DeWalt/Delta 7670 set has a low hook angle, and is on sale from Grizzly for $90 plus s/h. This one is a decent copy of the Forrest Dado King design. 24T cutters/4T chippers. An excellent bang for the buck.


The Freud SD/DD 208 and similar CMT 230.012.08 sets also have a low hook angle and are good sets, but both have half the tooth count of the DeWalt/Delta set, so they don't cut quite as cleanly. 12T cutters/2T chipeprs. The CMT set is on sale new from Reconditioned Sales for $67 plus s/h….excellent price for that set.


The Infinity Dadonator is a pretty amazing set IMHO but costs ~ $180….very reasonable by premium dado standards, but definitely more than the other bargain sets mentioned. 24T cutters/6T chippers.
