OVERVIEW

Get the Best Value with Pferd 62055 Flap Discs

When it comes to grinding and finishing stainless steel, you need an abrasive that works as hard as you do. The Pferd 62055 POLIFAN Flap Disc (4.5" x 7/8", 120 Grit) is built to deliver maximum value and performance. Known for their reliability, Pferd flap discs are a staple in welding shops across the country. This specific model combines the aggressive cutting action of Zirconia Alumina with a fine 120 grit, giving you the ability to smooth out welds and blend surfaces to a professional finish in record time.

The Type 29 conical shape is a favorite among welders for its versatility. It allows you to attack contours and edges with confidence, providing better leverage and surface contact than flat discs. This means you can grind more comfortably for longer periods, reducing fatigue during big jobs. The 120 grit is specifically suited for light grinding and finishing work, leaving a smooth surface that requires minimal rework. It is the ideal follow-up step after heavy stock removal with coarser grits.

Why choose Pferd? Because time is money. These discs are engineered to last longer than standard economy discs, meaning fewer stops to swap out worn abrasives. The integrated fiberglass backing is tough and safe, fitting directly onto your standard 4-1/2" angle grinder. Whether you are fabricating custom stainless parts, repairing equipment, or doing general maintenance, the Pferd 62055 is the reliable choice for a clean, cool, and consistent cut every time.

Applications

  • Weld blending and finishing on stainless steel tanks and vessels.
  • Surface preparation for painting or powder coating.
  • Deburring cut edges and machined parts.
  • General fabrication and maintenance repair operations (MRO).

FAQ

Type 27 discs are flat and best for finishing on flat surfaces at lower angles (0-15 degrees). Type 29 discs, like the Pferd 62055, are conical (angled) and are better for aggressive stock removal and contour work at steeper angles (15-25 degrees).

This disc uses Zirconia Alumina abrasive grain, which is durable and self-sharpening, making it ideal for tough materials like stainless steel and carbon steel.

No, this flap disc has an integrated fiberglass backing plate that mounts directly to the angle grinder, so no separate backing pad is required.

120 grit is a fine abrasive used for finishing, blending, and smoothing surfaces. It is typically used after coarser grits (like 40 or 60) to remove scratches and prepare the metal for polishing or painting.

While it can grind aluminum, Zirconia discs may load up (clog) faster on soft metals. For aluminum, discs specifically designed with a coating to prevent loading are recommended, though this will work for short tasks.

The maximum safe operating speed is typically 13,300 RPM for 4-1/2 inch flap discs. Always check the label on the disc to confirm.

It fits standard 4-1/2 inch angle grinders with a 7/8 inch arbor (spindle). This is the most common size for small angle grinders.
