Reply to comment by DadOfFan in dressing a cutoff wheel by DadOfFan
Read that reply, still doesn't seem right. In my 20+ years of using cutoff wheels I've never had to dress one, ever.

Yeah same here. Been using them forever and never had one clog up. Make sure it's for ferrous use if steel and for aluminum if aluminum.
Otherwise, toss it out and use a new one. They're cheap. Certainly cheap enough to not risk blowing one up.

Same, that's why I was asking. I am starting to think it may be the cut off wheels themselves.

You are using the wrong disc, based on your links.
The discs you've linked are for stainless, not mild steel.
Basically the different types of disc use a different binder (glue) which holds the abrasive particles together. The idea is for the disc to wear down just slightly faster than it builds up metal particles, so it doesn't clog.
You might recover the disc if you did a heavy (push hard) series of cuts on a couple of bits of scrap metal. It'll clog again though.
Continuing to use it as-is is dangerous as the heat generated by the rubbing action of the clogged disc will eventually cause the binder to break down and chunks of the edge of the disc will be ejected at high speed.
Whatever you decide to do, in terms of trying to recover the disc you have, you must have the guard in place (and correctly positioned) because there's a non-zero risk of bits of the disc coming off.
There's a reasonable argument that can be made for binning that disc (because it'll only clog again) and buying the right type for the metal you're cutting.

its for stainless/steel. Its in the information panel below the description.

Yeah I'm stumped. Never had this problem before with ferrous metals, unless somebody snuck in and used it to grind some aluminum without you knowing.
