3M™ Green Corps™ Depressed Center Wheel, 24 4-1/2 in x 1/4 in x 5/8-11 Internal
These 1/4 inch thick bonded wheels contain proprietary Cubitron™ Abrasive Grain and produce very high cut rates on a wide variety of metals.
As close to magic as you will ever find.
I was at a friend's shop and found this in a box with some other wheels. It must have been a sample from a vendor. Anyway I put this wheel on a 4 1/2" grinder and set to work. I was blown away. It cuts like a milling machine and the face stays nice and flat. Their cost is irrelevant. The increase in production and quality is worth whatever. I will give away all the other wheels I have. Oh, one other thing, they don't stink like resin bond wheels.
