You no longer have to make a calculation or test our flap discs, that we have already done for you. The FE flap discs have a high cutting capacity and retain grinding power. With our discs you do not have to exert extra hard pressure on the workpiece, which makes it much easier for the user to work. It is not only a long life which determines whether a disc is good but also determines how much material can be chipped and how fast it goes. The cheapest flapdisc in purchase is never the most economical drive in the total picture.
