62362 - PFERD POLIFAN SG A-COOL Flap Disc 4-1/2" x 7/8" 60 Grit Type 27

High-Performance Grinding for Aluminum and Stainless Steel

The PFERD POLIFAN SG A-COOL Flap Disc (SKU: 62362) is a specialized abrasive tool designed to overcome the common challenges associated with grinding materials that have poor thermal conductivity or a tendency to load. Part of PFERD's Performance Line SG, this disc is engineered for professional users who require optimum results and economic efficiency in demanding industrial environments.

Standard flap discs often fail when working with soft metals like aluminum because the material melts and clogs the abrasive grains—a process known as "loading." This renders the disc useless long before the abrasive is worn out. The POLIFAN SG A-COOL features a specific blend of Aluminum Oxide abrasive with active coolant additives. This top-sized abrasive coating significantly reduces heat build-up in the workpiece and prevents soft chips from adhering to the disc face. The result is a consistent cut rate and extended service life, even on gummy non-ferrous metals.

In addition to its performance on aluminum, this disc excels on stainless steel (INOX). The cool grinding action minimizes thermal stress, reducing the risk of heat discoloration (blueing) and the need for subsequent rework. The Type 27 (flat) profile allows for excellent surface blending and finishing capabilities. Constructed with a robust fiberglass backing, the disc is safe to use and will not smear or melt onto the workpiece, ensuring a clean, professional finish every time.
