8 inch Diamond Disc Grit 80

Got it, attached it to my Hi-Tech Diamond 8" I got off Amazon and it works like a charm.

I've put stones on a dop stick, and attached to a drill to shape stones. This blade seems to wear a bit where I am specifically using it, but I am not using it as intended. So far - if you're looking to shape stones, these work.

ok

I have found several uses for this lapping wheel but the main reason I got it was for squaring my custom knife handles. It mounts right on a 1/2 hp grinder and really removes some stock at the speed the grinder turns. The wheel seems well made with the diamond particles firmly attached. I can also use it for rough sharpening my knifes and chisels. I make custom knives and the handles are either wood, epoxy, bone/horn, or acrylic. This wheel can be used to square any of them. I can use a cork grinding belt cleaner to clean anything that sticks to the wheel. I'm happy with it.

I dont know if its my equipment or not but this disc made my flat lap shimmy and shake when up to speed. This is the first I have purchased for my new flat lap and since my lap is new I would suspect the disc.

Excellent

not good quality,wears out very fast.

Not perfect but pretty good. I attached it to an acrylic backing because it's pretty thin, but once attached it worked pretty well. The only issue I found is that one part of the grit was either badly adhered or a high spot because after a week or 2 of grinding there was a bare spot that had no grit. Not a big deal, I can still use most of the surface, but if I try to use the area where it wore away it bumps, catches, or chips the stone. (Not a big deal for 80 grit, I leave some wiggle room in case the grind is rough or chips)
