5" x .040 x 7/8" T1 High Performance 4X Ceramic Cutting Wheels

They last longer on thick material

fast service and great product

Best cut off wheel out there--

I've tried'm all. These last longer, and cut cleaner and faster than any other, thus far. (on mild steel at least) Walter Zips, Nortons, Sait, Pferd, tool brands, even Metabo- these are better and less expensive. I stand by it. --- just don't drop the grinder off the table. These wheels dont take a side impact very well. -- Of course, we all try not to drop a grinder anyway.
