Cut through a dozen 1/4-inch bolts and the edge still looks factory fresh, no warping or loading up on me. The 7/8 arbor fit my grinder perfectly, and the 4 1/2 size is just right for tight spots. This is the wheel I'll reach for first from now on.

I was a little worried about the .045 thickness, but it holds up well and makes clean cuts. Ground down some heavy welds on a trailer hitch without it loading up or wearing out too fast.

Cut through sheet metal like it’s butter, and the .045 inch thickness leaves a clean edge with no clogging. Very happy with how fast it works on my angle grinder.
