I already used for years Festool tools. The saw blade is a replacement sheet for me in case I have to bring the first sharpening. The quality is very good, clean cut and good cutting performance. The sheet is suitable for sensitive board materials and is stable. I saw a lot of OSB boards, doors and gypsum fibreboard. Together with the guide rail, the results are always perfect. Furthermore, the price of the saw blade In fact, half of the EIA by Festool. Is also original item and was delivered quickly. Surprised me, because Festool actually operates fixed price policy. So full marks and therefore clear recommendation!
