good quality at roark supply, one of the sponsors here I've been really impressed with their cut off discs.
leigh high valley is another source for grinding discs that last well and good pricing. I don't care for their cut off dics as much as the ones from roark
I asked 3 years ago. Here are the results from back then.

Same source.
I was running HF for years. The quality took a dump and I had to search out a new source.
