I got it hoping to save on the cost of changing the 40-tooth discs almost every day, while with this one I thought I could sharpen it. The fact that it is quite heavier than other similar 40-tooth discs might be manageable, but the negative to dangerous aspect is that its thickness is such that it barely "feminizes" at the head, resulting in the screw not tightening as it should. If I find a nest that fits perfectly, I will use it and come back, until then it will be on the wall. As for its cutting ability, YES it cuts well!!
