I was about to pull the trigger on the Rockler sale on the 8” Oshlun dado blade kit for $60.00 but remembered someone saying some saws do not have the power for an 8”. The table saw in question is the Ridgid R4511 granite table saw. It supposed to have a 1&1/2 horsepower motor. Would I be better off with the 6” instead? I just hate to buy the 6” when the 8” is cheaper, but ultimately wan’t the one that will perform better. I only plan to use it for building shelves, built-ins, cabinets etc and don’t think I would ever need a cut that was deeper than 3/4”. Any input or opinions would be greatly appreciated

I’m pretty sure it can handle an 8”, but considering the sudden proliferation of 4511s due to the sale that I missed out on cries briefly in the corner I’m sure one of other lucky LJs that scored one cries a little more has some first hand experience

Not sure what the Rockler sale on the 8” model is, but I got my 6” Oshlun last year for $45.00 at Rockler… VERY happy with it…

Right now the 6” are $70, and the 8” are $60

I’ve been running 8” Freud with nearly a full stack at times. Worked just fine – go with the 8.

The 8” offers more cutting depth (and more teeth) ....the extra depth isn’t needed often, but if you ever use a sled, the extra depth would be handy. Your saw should spin the 8” fine.

What? Not enough power to power an 8” blade? Someone step in and correct me if I’m wrong but I would be SHOCKED. I’ve got a Delta contractor saw- probably also 1.5 hp. Very comparible machine I would think. No problems with 8” blades.

Check the manual on your saw.

I checked my manual and it doesn’t say anything about what size to use, I have the same saw.

Thanks for all of the replies. I am going to get the 8”. Lots of good reviews, more teeth than the 6” on the chippers, and cheaper. I don’t see how I can go wrong. Cliffton, your review of the blade was what led me to looking at Oshlun! Did your saw fall under the arbor shaft recall? I just had mine done and they replaced the shaft so hopefully no flying dado blades will be in my future! Thanks again for all the feedback

I have an 8” Systi-Matic dado set that ran just fine on my old 1HP Craftsman TS, and even better on my 1.5HP Jet.

Nope mine wasn’t one of the recall ones, though when i fired it up and raised it through the ZCI I did stand to the side :D

Go for 8”. I have the 3660 and has never had issue using full stack 3/4 dado. If you ever use a sled, you will need 8”. if not then 6” will do.
