I am with mixed fillings about this one. the disk is very good. it cuts great and doesn't need replacing after few uses. but.. after the first long use, the plastic/nylon on it got melted it seems, plus the fact that it is very thin, made it impossible to release. I tried so hard my grinder release button stoped working. Only at a friends garage I was able to release. the disk is still usable. I would recommend peeling off some of the nylon before use...
SUPER SAW DISC, the builder i work with loves it,
