Which Porter Cable? One with an aluminum table (PCB220TS or PCB222TS) or a cast iron (PC270TS)? I think the ones with the aluminum table only takes up to 1/2” wide, and you should probably go with a 6” set. The cast iron table can take up to 3/4” wide, and you have your option of 6” or 8”. The 6” would be less taxing on the saw.

Depth of cut is an advantage on the 8”, but takes more power to spin.

6” doesn’t take as much power to spin but depth is limited to your max depth of cut minus 2”. You get another 1” out of the 8” but it takes some juice to turn a full 3/4” stack. I’m just stating what little I know but I’ve never used a full stack.

What model saw do you have? Normally the 6 inch dado blade set will work, unless you’re doing some projects that require more depth or are using a sled…also as paxorion mentioned, need to keep an eye on the width with your machine. Some smaller machines limit the diameter to 6 inch as well.

Your machine is capable of running an 8” stack. I have an 8” and 6” oshlun stacked dado sets, I’ve used the 8” once to try it out. Everything I use a stacked dado set for has been fine with a 6” set, it takes less stress to run.

I have the oshlun 8” dado, I use on my unisaw. Comes with shims and extra blades to make adjusting for undersized plywood easy. Bought mine from carbide processors, great service, fast delivery, bought along with a couple other blades, got free shipping as well. Their prices and quality are very good. Have no connection with the company, just a happy customer.
