Have approximately 10 granite bristle A (100x25x8cm) cut. Then the thing was floored. Have ordered three because I have cut more than 10 pieces. Previously had a Makita disc (using a 230 mm Makita) the three times, however, costs max. 2 slices longer has cut and then was also flat. Would go back as process if I know that I have to cut more in succession. But should decide what he is willing to spend any himself.
