Using a cutting wheel in a grinding orientation to feather the edges of a weld or deburr the edge of the material — not the way it was designed to be used — may seem more convenient than changing the abrasive. But it puts significant stress on the wheel that can result in the product breaking down prematurely or worse; product failure.
