All Purpose Abrasives have devised polifan curve flap discs for fillet weld grinding, deburring and chamfering applications.
The flap discs are a PFERD innovation and they are available with ceramic grain flaps. The unique radial construction shape, along with cutting-edge flap design makes these flap discs perfect for difficult or demanding work on fillet welds.
The flap discs produce highly abrasive grinding in a short period of time due to high stock removal, and grinding out of fillet welds is extremely precise.
Dimensional stability is guaranteed with these flap discs, which ensures for high quality work results.
The flap discs are highly durable resulting in excellent tool life when working on fillet welds, and they optimise use of the grinding materials on the radius.
Thanks to the ceramic nature of the grain flaps, cool grinding can be applied to those materials with poor heat-conducting capabilities. This prevents thermal damage yet at the same time ensures optimum grinding results are still produced.
