I had a chance to try the two new offerings from Kingsley-North in a friend's shop recently and I thought it appropriate to pass on some positive observations. 1. Agglomerate silicon carbide belts - mfrd in Germany and about double normal sic belts (but still only $4.70), these belts have the feel of a heavier coating of silicon carbide grit. Let me say first off, they are aggressive. They come in grits from 80 to 1200, but my sense was that they were aggressive enough to use a higher grit number in place of what you would use normally. Using a 600 felt more like a 200 ish performance. The surface texture is rough enough that they do require a bit of caution as to skin contact with a turning belt. I can easily see situations where they would be preferable to a standard belt and even a diamond wheel. I do plan to order some for my dual expando machine just to see how long they last and perform after some prolonged use.
2. 8" diamond wheel (2" wide). So more wheel width than your standard 1.5" wide wheel and a reasonable price $108 for either the 80 or 220 grit. Although I had only limited time on this wheel, being in the market for a coarse diamond wheel, I'm going to order one of these. The diamond wraps around the side of the wheel, but its impossible to tell if its nearly that thick on the contact surface of the wheel. I had trouble finding these products on their catalog site, but there is a full page ad in Rock and Gem magazine. Buyer beware; I don't work as a shill for KN but thought they products worthy of mention.

Yes, we have subjected them to hard use. They have certainly lasted and at the current prices constitute good value and quality results for the money. I'll still have my 3m diamond belts for 3000 and above.

So do you find them giving the same polish results, only quicker and lasting longer? ie normal 800 grit == agglomerate 800 grit etc? Thanks.
