62220 - Pferd POLIFAN PSF Z-STEEL Flap Disc 4-1/2 Inch 80 Grit Type 29

Superior Steel Grinding with Pferd POLIFAN Technology

The Pferd POLIFAN Type 29 Flap Disc (SKU: 62220) represents the pinnacle of abrasive engineering for the professional metalworker. Part of the renowned PSF Z-STEEL line, this 4-1/2 inch disc is engineered specifically to tackle the demands of carbon steel fabrication. Unlike standard aluminum oxide discs, this model utilizes high-performance Zirconia Alumina grain. This advanced abrasive material is self-sharpening; as the grains fracture under pressure, they reveal new, sharp cutting edges, ensuring consistent cutting action throughout the lifespan of the disc.

The "Type 29" classification denotes a conical shape, where the flaps are arranged at an angle. This geometry is critical for aggressive stock removal and is particularly effective when working on contours, edges, and weld seams. It allows the operator to maintain a comfortable working angle (typically 15 to 25 degrees) while maximizing surface contact area for faster material removal rates. The 80 grit specification places this disc in the intermediate range, making it an excellent choice for blending welds, removing light scale, and preparing surfaces for painting or further finishing steps without gouging the workpiece deeply.

Durability is a hallmark of the Pferd brand. The flaps are securely bonded to a robust backing plate that resists warping and vibration, providing a stable platform for high-torque angle grinders. This stability not only improves safety but also reduces operator fatigue by minimizing vibration transfer. Whether you are deburring flame-cut parts, grinding fillet welds, or chamfering edges, the Pferd 62220 delivers a superior balance of speed and longevity. It is designed to withstand higher contact pressures, making it ideal for industrial environments where efficiency and throughput are paramount.

By integrating the grinding and blending steps into a single tool, this flap disc significantly reduces process time compared to using hard grinding wheels followed by fiber discs. The layered flap construction also runs cooler than solid wheels, reducing the risk of heat discoloration on the workpiece. Equip your shop with the Pferd POLIFAN Z-STEEL series for reliable, heavy-duty performance on all your ferrous metal projects.
