When I bought my PM 66 in 1974 the carbite tipped blades cost to much for us poor folks. I bought a set of steel da-do blades form sears for under $50, about 2-3 years later again sears had a set of carbite da-do blades on sale for under $100. Alot of design changes have been made to the da do set now sold.

What do you guys buy without getting robbed that leave a flat bottom and do not spinter plywood?

If you don't need to cut a lot of dadoes, you could get a rip blade with flat top teeth, or an ATB blade with a raker. You then make your to outside cuts, and then move your fence slightly, and make a cut. Do this until the dado is cleared out. It can be slow, but gets the job done without an expensive dado set.

Freud makes a nice dado set for a reasonable price. Not carbide but they work well. You can have them sharpened.

I've got a Freud Super Dado carbide 6" set, but your cabinet saw can handle the 8" set.  I believe it was around $175. However, the 8" will be a bit more.  It has proven to be a very good quality set.  The key to getting very little tearout is a zero clearance insert to support the fibre pull during the cut.

I have a Freud 8" dado set that cost $100.  Does a good job.  You can make an insert out of plywood and raise the blade up through the insert for a custom fit.

Some Da-do blades have only 12 teeth, other have up to 40. Which one would you recommend, if the price per tooth was the same?

WDH

More teeth makes for a smoother cut.  It also makes for a slower cut.  If you aren't cutting dado's all day long, I would opt for the smoother cut.

If you can go to a school auction or the like, many times you can buy stacks of carbide blades. I just put "machine washers" (the precise ones) in between and make my own stacked head. I have other factory stacks, but this is by far my favorite.

I always liked the stacked sawblade dado head the best.  I had a wable head dado once and only used it once . That was a pile of crap. I also have a set or two of the regular dado with the stacking rakers, but I don't like them to much.

The newer da-do set have multiple tipped cutters on the insides chipper. Does this style da-do make a smoother bottom?

I use a da-do on my table saw and on my radial arm saw,  what should I look for in a da-do set  that would work equally well on both of these machines?

The Freud SD500 Series Chip-Free Dado Sets are good ones.
Use on both the radial and table saws, equally well.

I like stacked blades with a combination blade like teeth. The best luck I've had on plywoods and splintery woods was with dado blades with a negative tooth angle, if the teeth have the more aggressive positive angle it grabs the wood more and you'll have more tearout.

Anymore I try to plan all my dado cuts around my router bit sizes, they're cheaper easy to sharpen and fairly easy to control tear out using tape.

I was checking to see what Amazon had in the line of saw blades, they handle the Freud and a company named Oshlun. Does anyone know anything about them? They have a 42 tooth, 8 inch da-do set under $90.

I read the feedback reports on the Freud da-do blades and they where complaining about chipped carbites as received.

All my Freud blades have been very good quality.

The OSHLUN da-do blade is the same design as the high priced Freud, they have over forty teeth on the outside blades and have 6 teeth on  the chippers. The design is good but I have never heard of them, they don't show up  in any of the wood  worker magazines.

Any body know anything about Oshlun?

I use a wobble to rough out slots.  Routers or rabbetting planes, chisels, whatever to clean up to the level I'm shooting for.

Some guys just like smooth bottoms, eh? :D :D

Hello everyone.  I just registered and this is my first post.  I have the Freud  8" Super DaDo and it does an excellent job as others have said.   I also use a router table and router bits, sometimes they are better for the job especially if it is a stopped dado.   What little knowledge I might have I am glad to share.

I still have not bought a new da-do, I still have not made up my mind on what tooth profile I should get. Would you get  a ATB or a triple chip grind, or a + or - bevel hook angle?
