I was hoping the price wouldn't disappoint me. This, combined with a 4" damo polisher and pads, a small wet saw, another 7" saw with a diamond blade, epoxy, and clamps was just what I needed to create a pretty darn nice round nose blade on granite 3 /4 to produce. I've only done about 10 feet of bullnose with it so far, but this thing shows no wear. Keep the revs fairly low. In the illustration, the factory edge is the left edge. The edge I made with it is the right side.
