The surface cleans well on a wide area, but the floor cleaning is not so good on a small area. The carbide mold leaves a crown in the center. If you don't move past the middle of the cut, it leaves a high point. When it came out of the box there were 3/16" chips in the carbide on both sides in the middle. This won't affect the armor as the center doesn't touch, so I left four stars. Doesn't work for me because I'm looking for a flat machined surface when dipping.
