Flap discs go from rough grinding to smooth finishing in one step

POLIFAN®-Curve flap discs from Pferd Inc. are designed for rough and finish grinding in fillet weld applications. The patented, proprietary design goes from rough grinding to smooth finishing in a single step.

The tool removes weld seams and slag, leaving a finish smooth enough for identification of cracks, inclusions, and porosity in the fillet during weld inspections, says the company.

This disc’s configuration offers three usable working surfaces—the top face, bottom face, and entire radial edge—as opposed to the single surface of a conventional flap disc. This allows the disc to grind fillet welds as well as unusual curves. The discs are available in a number of diameters (4½, 5, 6, and 7 in.) and abrasives (zirconia, aluminum oxide for aluminum, and ceramic oxide) and with a 7/8-in. arbor hole or quick-change 5/8-11-in. hub.
