OVERVIEW

Professional Grade Finishing for Steel Fabrication

When your project demands a flawless finish on steel, the Pferd 62576 POLIFAN Flap Disc delivers the reliability and performance professional welders trust. This 7-inch abrasive disc is built to tackle the tough jobs found in shipyards, fabrication shops, and construction sites. Powered by Zirconia Alumina grain, this flap disc cuts cooler and lasts longer than traditional aluminum oxide alternatives. The 120 grit configuration is perfect for that final step in your grinding process, smoothing out rough grind marks and leaving a clean, uniform surface ready for inspection or painting.

Time is money in any welding shop, and the Pferd POLIFAN series is designed to save you both. The "Superior" classification isn't just a name; it represents a specific formulation optimized for steel. This means the abrasive doesn't glaze over or dull prematurely when grinding ferrous metals. You get a consistent bite from the first spark to the last, reducing the frustration of working with discs that lose their edge halfway through the job. The 7-inch size is a powerhouse for larger angle grinders, giving you the reach and surface area coverage needed to breeze through long weld seams and large panels.

The Type 29 conical shape of this disc is a favorite among fabricators for its versatility. The angled flaps allow you to attack the work surface at a comfortable angle, providing excellent leverage for digging into corners or smoothing out contoured welds. This shape maximizes the contact area, ensuring you aren't just grinding with the very edge of the disc, which can lead to gouging. Instead, you get a smooth, controlled blending action that makes weld transitions disappear.

Durability is key with the Pferd 62576. The flaps are securely bonded to a strong backing plate, ensuring safety and stability even at high RPMs. Whether you are cleaning up spatter, blending a multi-pass weld, or preparing a surface for a critical coating, this flap disc provides the control and finish quality you need. Upgrade your abrasive inventory with Pferd's German-engineered quality and experience the difference in your daily grinding tasks.

FAQ

Type 27 discs are flat and best for blending and finishing on flat surfaces at lower angles (0-15 degrees). Type 29 discs, like this Pferd model, are conical (angled) and are better suited for aggressive stock removal and contour work at steeper angles (15-25 degrees).

While Zirconia alumina can cut aluminum, this specific disc is optimized for steel ("Steel Superior"). Using it on aluminum may cause the disc to load up (clog) quickly. It is recommended to use a disc specifically designed for non-ferrous metals or aluminum to prevent loading.

The "Superior" line is Pferd's high-performance category designed for specific materials. In this case, it indicates the disc is optimized for maximum service life and stock removal rates specifically on steel, offering a better cost-to-performance ratio than general-purpose discs.

This disc has a 7/8-inch arbor, which is the standard mounting size for most 4.5-inch, 5-inch, and 7-inch angle grinders.

No, 120 grit is a fine abrasive intended for finishing, cleaning, and blending. For removing heavy welds or aggressive stock removal, a coarser grit like 40 or 60 is recommended.

No, flap discs have a built-in backing plate (usually fiberglass or plastic) and do not require a separate backing pad like fiber discs do. They mount directly to the angle grinder.

Zirconia Alumina (Z) is tougher and more durable than standard Aluminum Oxide. It has self-sharpening properties that allow it to cut faster and last longer, especially under the high heat and pressure generated when grinding steel.
