OVERVIEW

Industrial Grade 7-Inch Flap Disc for Heavy Steel Fabrication

The Pferd 62228 POLIFAN Flap Disc is a premium abrasive tool designed for industrial applications requiring rapid stock removal and extended durability. Part of the Superior line, this 7-inch disc utilizes high-quality Zirconia Alumina grain, a material renowned in the industry for its toughness and self-sharpening properties. Unlike standard aluminum oxide discs that dull relatively quickly, Zirconia Alumina fractures under pressure to reveal fresh, sharp cutting edges, maintaining a high cut rate throughout the lifespan of the product. This makes it an economical choice for high-volume fabrication shops where downtime for disc changes needs to be minimized.

Engineered with a Type 29 conical profile, this flap disc features angled flaps that provide a larger surface area contact when the grinder is held at a standard 15 to 25-degree angle. This configuration is particularly advantageous for aggressive grinding, edge chamfering, and weld leveling on steel structures. The 40 grit specification indicates a coarse abrasive texture, specifically selected for heavy-duty tasks such as grinding down heavy weld seams, removing deep scale, or shaping metal edges prior to welding. The 7-inch diameter offers significantly more abrasive material than smaller 4.5-inch or 5-inch counterparts, making it ideal for working on large surface areas like tanks, pipes, and structural beams.

Pferd's manufacturing process ensures a robust construction where the abrasive flaps are securely bonded to a durable backing plate. This design absorbs vibration and allows for high contact pressure without failure, providing the operator with stability and control. The 7/8-inch arbor hole is the industry standard for 7-inch angle grinders, ensuring broad compatibility with existing power tools in your facility. Whether used for shipbuilding, structural steel erection, or general heavy machinery maintenance, the Pferd 62228 delivers the consistent performance professionals demand.

FAQ

Type 27 discs are flat and best for blending and finishing on flat surfaces. Type 29 discs, like this Pferd 62228, are conical (angled), which makes them more aggressive and better suited for contour work, edge grinding, and heavy stock removal.

This specific disc is part of the 'Steel Superior' line and features Zirconia Alumina grain, making it optimized for use on carbon steel and other ferrous metals.

40 grit is a coarse abrasive rating. It is designed for heavy stock removal, such as grinding down large welds or shaping metal, rather than fine finishing or polishing.

No, you must never use a disc that is larger than the tool's rating. A 7-inch disc requires a 7-inch or 9-inch angle grinder with the appropriate guard and speed rating.

Zirconia Alumina is a tougher, self-sharpening grain that lasts longer and cuts faster than Aluminum Oxide, especially under the high pressure and heat generated during heavy steel grinding.

The arbor size is 7/8 inch, which is the standard mounting size for most 7-inch and 9-inch angle grinders.

No, flap discs have a built-in backing plate. You do not need a separate rubber backing pad like you would for a resin fiber disc.
