OVERVIEW

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.

FAQ

Type 27 discs are flat and best for blending on flat surfaces and finishing. Type 29 discs, like this one, are conical (angled), which provides better surface contact at steeper angles, making them ideal for contouring and aggressive stock removal.

This disc is optimized for use on steel and other ferrous metals. The Zirconia Alumina grain performs exceptionally well on carbon steel.

80 grit is a medium-fine abrasive. It is used for intermediate grinding, blending welds, and surface finishing. It removes material slower than 40 or 60 grit but leaves a smoother finish.

Standard 7-inch flap discs are typically rated for a maximum of 8,600 RPM. Always check the label on the disc itself to ensure your grinder does not exceed the safety rating.

Zirconia Alumina is tougher and more heat-resistant. It self-sharpens during use, providing a faster cut rate and significantly longer life, especially on harder materials like steel.

No, flap discs have a built-in backing plate (fiberglass in this case) and do not require a separate backing pad like fiber discs do.

While Zirconia can be used on stainless, it is primarily optimized for steel. For dedicated stainless steel work, a specialized disc with cooling agents or ceramic grain is often recommended to prevent heat discoloration.
