62222 - Pferd POLIFAN SG Steel 4-1/2 Inch 40 Grit Type 29 Flap Disc

High-Performance Grinding with Pferd POLIFAN SG Steel

The Pferd 62222 POLIFAN Flap Disc is a premium abrasive solution engineered for the most demanding industrial applications. Part of Pferd's renowned Performance Line SG, this tool is specifically designed to maximize efficiency when working with steel. The disc features high-quality Zirconia Alumina Z grain, a tough and aggressive abrasive that excels at rapid stock removal. Unlike standard aluminum oxide discs, Zirconia Alumina possesses self-sharpening characteristics; as the grains fracture under pressure, they reveal new, sharp cutting edges, ensuring that the disc maintains a high cut rate throughout its entire service life.

This specific model utilizes a Type 29 conical profile. The angled design of the flaps allows for greater surface contact when the grinder is held at a natural working angle (typically 15 to 25 degrees). This geometry is particularly advantageous for contour work, edge grinding, and weld seam removal, as it allows the operator to apply higher contact pressure without gouging the workpiece. The flaps are securely bonded to a durable fiberglass backing plate, which provides the necessary rigidity for heavy-duty grinding while absorbing vibration to reduce operator fatigue.

The "Steel" designation indicates that the bonding system and filler agents are optimized for carbon steel applications. This prevents the glazing often seen with general-purpose discs and ensures cool, fast cutting on ferrous metals. With a coarse 40 grit rating, this disc is the ideal choice for the initial stages of fabrication, such as leveling heavy welds, removing deep scratches, or chamfering edges prior to welding. Industrial professionals rely on the Pferd 62222 for its consistency, safety, and superior cost-to-performance ratio.

Key Industrial Benefits:

• Aggressive Removal: 40 grit Zirconia grain removes material rapidly, reducing cycle times.
• Long Service Life: Durable construction and premium grain extend the interval between disc changes.
• Ergonomic Design: Type 29 shape and vibration-dampening backing improve operator comfort.
