OVERVIEW

Industrial Grade Stainless Steel Grinding

The Pferd 63033 POLIFAN Flap Disc is engineered for industrial environments where efficiency and finish quality are paramount. This 5-inch abrasive disc features a Type 29 conical profile, which is specifically designed to provide aggressive stock removal while maintaining a comfortable grinding angle. The conical shape allows for greater surface contact area compared to flat discs, making it the preferred choice for contouring, edge grinding, and weld seam blending on complex workpieces.

Equipped with 80 grit zirconia alumina abrasive, this disc is optimized for intermediate finishing tasks. It bridges the gap between heavy stock removal and final surface polishing, leaving a consistent scratch pattern that is easy to blend. The "SS Value" designation indicates a formulation specifically tailored for Stainless Steel (INOX) applications. It is manufactured free of ferrous, chlorinated, and sulfurous fillers, ensuring that the workpiece remains free from contamination that could lead to corrosion. This makes it an essential consumable for fabrication shops handling food-grade equipment, architectural stainless, or chemical processing vessels.

Durability is a hallmark of the Pferd POLIFAN line. The robust backing plate supports the abrasive flaps securely, allowing for high application pressures without failure. As the flaps wear down, fresh, sharp abrasive grain is continuously exposed, maintaining a consistent cut rate throughout the life of the disc. This self-sharpening action reduces downtime associated with frequent disc changes, thereby improving overall shop productivity. Compatible with standard 5-inch angle grinders using a 7/8-inch arbor, this disc is a versatile addition to any MRO inventory.

FAQ

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

While it can physically grind aluminum, this disc is optimized for stainless steel and steel. Grinding aluminum with standard zirconia discs can lead to 'loading' (clogging) of the flap. A disc specifically designed for non-ferrous metals is recommended for aluminum.

No, this Pferd POLIFAN flap disc comes with an integrated backing plate. It mounts directly to your angle grinder using the standard locking nut or flange.

80 grit is considered an intermediate to fine grade. It is used for light stock removal, blending, and smoothing out surfaces after a coarser grit (like 40 or 60) has been used, or for single-step finishing on lighter welds.

Yes, this disc is generally suitable for stainless steel (INOX) as it is designed to be free of iron, sulfur, and chlorinated fillers that cause contamination and rust, making it safe for use on stainless steel intended for various applications.

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

Flap discs grind and finish in one step, run cooler, and vibrate less than solid grinding wheels. They are generally more forgiving and leave a smoother finish, whereas grinding wheels are faster for very heavy stock removal but leave a rougher surface.
