The patented POLIFAN-STRONG flap discs from PFERD reportedly remove more material in less time than most other consumable abrasives for angle grinders. Featuring a unique extended flap design for consistent and extremely aggressive grinding up to the last grain, this disc delivers optimal performance for high-powered angle grinders. The combination of maximum metal removal and long tool life cuts downtime by reducing tool changes and lessens labor costs by reducing grinding time.

POLIFAN-STRONG flap discs are finding numerous uses in areas such as steel construction, foundries, ship building, automotive, tank construction, fabrication and pipeline work. The coated flaps are produced with a high-performance zirconia alumina abrasive, available in 36-grit for coarse grinding of steel and weld seams or 50-grit for work on edges such as chamfering and deburring. The discs are available in 4½, 5 and 7 in. diameters with either plain 7/8 in. bore or 5/8–11 threads.

  • abrasive


    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • chamfering


    Machining a bevel on a workpiece or tool; improves a tool’s entrance into the cut.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
