OVERVIEW

Smooth Finishing for Professional Welders

When your weld is complete and it's time to make it look professional, the Pferd 62259 POLIFAN Flap Disc is your go-to abrasive. Designed for the welder who cares about the final aesthetic and structural integrity of their work, this 120 grit flap disc excels at blending and finishing. The fine grit allows you to take a rough grind down to a smooth, uniform surface, removing scratches and imperfections without gouging the base metal.

The Type 29 conical shape is a favorite among fabricators because it allows for more aggressive engagement when needed. By angling the flaps, Pferd ensures you can attack edges and corners effectively, while the flat areas of the flaps can still be used for smoothing. The Zirconia Alumina grain is specifically formulated for steel, providing a fast cut that doesn't glaze over. This means you spend less time changing discs and more time finishing jobs. It fits any standard 4-1/2" angle grinder with a 7/8" arbor, making it a versatile addition to any tool crib.

Why choose Pferd? Because time is money. Cheap discs wear out fast and vibrate, causing hand fatigue. The POLIFAN series is built to run smoother and last longer. The 62259 model is particularly effective for "Steel Super" applications where standard discs fail to perform. Use this for cleaning up spatter, deburring cut edges, and blending TIG or MIG welds on mild steel projects.

FAQ

Type 27 discs are flat and best for blending on flat surfaces at low angles (0-15 degrees). Type 29 discs, like this Pferd 62259, are conical (angled) and are better suited for aggressive grinding and contour work at steeper angles (15-25 degrees).

While Zirconia Alumina can cut stainless steel, this specific 'Steel' line is optimized for carbon steel. For stainless steel, Pferd recommends their INOX-rated discs to prevent cross-contamination and ensure optimal performance.

120 grit indicates a fine abrasive texture. It is used for finishing, smoothing, and blending surfaces rather than heavy stock removal. It leaves a smooth finish suitable for painting.

The maximum operating speed for this 4-1/2 inch flap disc is typically 13,300 RPM. Always check the label on the disc to ensure your grinder does not exceed this speed.

No, this flap disc comes with an integrated fiberglass backing plate. It mounts directly to the angle grinder using the standard flange nut or quick-change nut.

Zirconia Alumina discs generally last significantly longer than Aluminum Oxide discs because the grain is self-sharpening and more durable, making them more cost-effective for industrial use.
