Polifan-Curve flap discs from Pferd Inc. are designed to provide a fast, productive and economical way to go from rough grinding to smooth finishing in a single step, particularly for fillet weld applications. The discs remove weld seams and slag, leaving a finish smooth enough for easy identification of cracks, inclusions and porosity in the fillet during weld inspections. Unlike conventional flap discs, Polifan-Curve provides three fully-usable working surfaces—the top face, bottom face and entire radial edge—making this tool suitable for grinding fillet welds as well as unusual curves such as those found in ornamental pieces. The flap discs also produce good results in contour grinding, removing material faster than bonded wheels and leaving a smooth finish for easy visual inspection. The larger-diameter discs provide deeper reach and have more coated material for long disc life. With minimal loss of diameter with wear, high productivity is sustained through the life of the disc, the company says.
The flap discs are available in a variety of diameters (4½", 5", 6" and 7") and abrasives (Zirconia, A/O for aluminum and ceramic oxide). They are also available with a 7/8" arbor hole or quick-change 5/8"-11" hub.
