Review on Diamond Dresser Single Grinding Tapered by Keith Alvord

I've used this to repair some really (some haha) terrible cobalt brand grinding wheels. I bought two Cobalts for my recently purchased Baldor grinder. Wheel balance was terrible. This cutter/dresser works very well. I don't have a holder/feeder so I just held the tool on the tool tray and slowly moved it from left to right. Not super accurate, but still greatly improved wheel balance.
