I just found a steal of a deal today at a garage sale a brand new Freud 8” dado set for $10.00. The people selling it said that they found it in the garage shelving when they bought their house. I was so excited as I was wanting to purchase one for the longest time. Reading the manual that came with the saw it said that it will only accept a 6” dado. The blade fits as I put it on just haven’t fired it up. Anyone out there using a 8” dado on this saw?

Why would they say only six inch? The only reason that I can think of is if the riving knife lock is in the down position it will hit. But since you don’t use a riving knife then leaving it up in the open position is fine.

What is your thoughts?

8” creates more rotational torque than the saw can handle. You risk screwing up the arbor on your saw.

If you have a local woodworking club, I’m guessing you’ll find someone to trade with you in no time at all.

You have a direct drive universal motor in that saw, which is not designed to handle larger blades. You can probably get away with using it for a limited time, but eventually, it will tear up your motor.

Don’t those universal motor saws run at a higher RPM than induction motor saws.
That would be a major reason to limit the diameter.
Still comes down to the potential torque load of course because the dado blade is heavier than a normal blade.
