PFERD Inc. has introduced the POLIFAN Z SG-POWER flap disc. The new flap disc features product enhancements that reportedly deliver up to 236 percent longer tool life than conventional flap discs. In addition to its dramatically increased tool life and higher aggressiveness, the new POLIFAN Z SG-POWER flap disc maintains consistent performance throughout the entire life of the tool yielding maximum economic value for the user.

This high-performance, zirconia alumina abrasive handles demanding grinding work, delivering optimal stock removal on high-powered angle grinders at higher contact pressures. It is available in grit sizes 40 and 60 in a type 29 (conical) shape. Manufactured without the addition of fillers, the new POLIFAN Z SG-POWER flap disc is rated for use on stainless steel (INOX) and steel. It excels in work on weld seams, chamfering and surface grinding steel.

POLIFAN Z SG-POWER lets users sustainably reduce vibration, noise and dust levels. In addition, the new flap discs provide for long, fatigue-free and resource-saving work, with excellent results in the shortest possible time.

POLIFAN Z SG-POWER flap discs are available in 4.5, 5 and 7-in. diameters with either 5/8-11 threaded or 7/8 in. plain arbor hole.

    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.

  • arbor


    Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.

  • 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.

  • surface grinding

    surface grinding

    Machining of a flat, angled or contoured surface by passing a workpiece beneath a grinding wheel in a plane parallel to the grinding wheel spindle. See grinding.
