OVERVIEW

High-Performance Zirconia Flap Disc for Steel Finishing

The Pferd 62259 POLIFAN Flap Disc is a premium abrasive tool engineered for industrial metalworking professionals who demand consistency and durability. Part of Pferd's renowned POLIFAN line, this 4-1/2 inch disc features high-quality Zirconia Alumina grain, a material celebrated for its toughness and self-sharpening characteristics. Unlike standard aluminum oxide discs that dull quickly, Zirconia Alumina fractures during use to reveal fresh, sharp cutting edges, ensuring a high removal rate throughout the lifespan of the disc.

This specific model is a Type 29 conical disc, designed with angled flaps that allow for greater surface contact when the grinder is held at a steeper angle (typically 15 to 25 degrees). This geometry makes it exceptionally effective for contour work, edge chamfering, and aggressive weld grinding where leverage is required. The 120 grit rating places this disc in the finishing category, making it the ideal choice for the final steps of surface preparation, blending weld seams until they are smooth, or preparing steel surfaces for painting and coating.

Optimized for use on steel and ferrous metals, the Pferd 62259 minimizes heat buildup, reducing the risk of thermal discoloration on the workpiece. The robust fiberglass backing plate provides stability and safety, absorbing vibration to reduce operator fatigue during extended use. Whether used in heavy fabrication, structural steelwork, or general maintenance, this flap disc delivers the reliability expected from German-engineered abrasives.

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.
