62575 - Pferd POLIFAN 7-Inch Zirconia Flap Disc 80 Grit Type 29

Industrial Grade Zirconia Flap Disc for Heavy Fabrication

The Pferd 62575 POLIFAN Flap Disc represents the pinnacle of abrasive technology for industrial steel fabrication. Engineered with high-performance Zirconia Alumina grain, this 7-inch disc is designed to withstand the rigorous demands of heavy-duty grinding applications. The Zirconia grain is renowned for its toughness and self-sharpening properties; as the grains fracture under pressure, they reveal new, sharp cutting edges, ensuring a consistent cut rate and extended service life compared to standard aluminum oxide discs. This makes the 62575 an economically superior choice for high-volume production environments where downtime for disc changes translates to lost revenue.

This specific model features a Type 29 conical profile. Unlike flat (Type 27) discs, the Type 29 shape is angled, allowing for a greater surface area contact when the grinder is held at a natural 15 to 25-degree angle. This geometry is particularly advantageous for contour work, edge chamfering, and weld blending, as it allows the operator to apply higher contact pressure without gouging the workpiece. The 80 grit abrasive size places this disc in the intermediate to finishing category, making it ideal for the second step in a grinding process—removing coarse grind marks left by lower grits or for single-step blending on cleaner welds.

Pferd's "Superior" line is formulated to optimize the balance between stock removal rate and disc longevity. The robust fiberglass backing plate provides necessary rigidity for safety while offering enough flex to absorb vibration, reducing operator fatigue during prolonged use. Compatible with standard 7-inch angle grinders featuring a 7/8-inch arbor, this disc is rated for high-speed operation, ensuring compatibility with pneumatic and electric tools commonly found in shipyards, structural steel plants, and general fabrication shops. By integrating the Pferd 62575 into your abrasive inventory, you ensure a high-quality finish on steel components while maximizing consumable efficiency.
