We recently got some new grinding discs at work they are a red ceramic abrasive (Not aluminum oxide) and they seem to last 4 to 5 times as long. there is not any info on the reverse side except grit size and the word ceramic. Not even where they are made. Does anybody know who makes these? I'd like to get some belts with this abrasive. I've used the blue zirconia, They are not worth the extra expense over aluminum oxide, the orange ceramic are a huge jump over the A/O and the blue zirc. but these red ceramic are even better than the orange.
