OVERVIEW

Premium Performance for Industrial Grinding

The Pferd 60625 Polifan SG Zirkon-Extra Flap Disc represents the pinnacle of performance in the Zirconia Alumina category. Designed for the most demanding industrial environments, this abrasive tool is engineered to deliver a superior balance between aggressive stock removal and exceptional service life. Part of Pferd's renowned Performance Line (SG), this disc is specifically formulated to outperform standard market alternatives by providing significantly more grinding capacity per unit.

At the core of the 60625 is a high-quality Zirconia Alumina Z grain. This self-sharpening abrasive is tougher and more durable than standard aluminum oxide, making it the ideal choice for high-pressure grinding applications on hard materials like steel and stainless steel (INOX). As the grains fracture during use, they reveal new, sharp cutting edges, ensuring that the cut rate remains consistent from the first spark to the last. This mechanism prevents the glazing and dulling often associated with lower-quality abrasives, maintaining productivity throughout the disc's lifecycle.

What truly sets the SG Zirkon-Extra apart is its construction density. It is built with approximately 40% more abrasive material than comparable standard flap discs. This "Extra" designation translates directly to operational efficiency; operators can grind longer without stopping to replace the disc. This reduction in downtime, combined with the extended life of the product, results in a lower total cost of operation for fabrication shops and manufacturing facilities. The Type 29 conical shape features angled flaps that allow for greater surface contact at standard grinding angles (15-25 degrees), making it particularly effective for contour work, edge grinding, and heavy weld seam removal.

The disc is constructed on a durable fiberglass backing that requires no additional support pad. This backing is designed to trim down as the flaps wear, allowing full utilization of the abrasive material. With a maximum speed rating of 13,300 RPM, the Pferd 60625 is compatible with standard 4-1/2 inch angle grinders, making it a versatile and essential tool for MRO professionals, metal fabricators, and industrial welders seeking to optimize their surface finishing processes.

INCLUDED

  • 1x Pferd Polifan SG Zirkon-Extra Flap Disc (4-1/2" x 7/8" - 36 Grit)

APPLICATIONS

  • Weld Removal: Aggressive leveling of heavy weld seams on steel and stainless steel.
  • Edge Chamfering: Preparing metal edges for welding (beveling) or deburring sharp cuts.
  • Surface Grinding: Removing mill scale, rust, and heavy corrosion from structural steel.
  • Contour Work: Grinding inside corners and curved surfaces due to the Type 29 conical shape.
  • Fabrication: General heavy-duty metal fabrication in tank building, structural steel, and automotive industries.

FAQ

Type 27 discs are flat and are best used for blending and finishing on flat surfaces at lower angles (0-15 degrees). Type 29 discs, like this Pferd 60625, are conical (angled) and are designed for more aggressive stock removal and contour work at steeper angles (15-25 degrees).

While Zirconia Alumina can cut aluminum, it is not the optimal choice as the soft metal may clog (load) the flap disc quickly. For aluminum, specialized discs with coatings to prevent loading are recommended. However, for occasional use, it will work if used with a lubricant or wax.

'SG' stands for Pferd's Performance Line (Special Grade), indicating a step up from their standard PSF line. 'Zirkon' refers to the Zirconia grain, and 'Extra' signifies that the disc is packed with approximately 40% more material for a longer service life.

No, this flap disc comes with a rigid fiberglass backing plate integrated into the design. You mount it directly to your angle grinder using the grinder's retaining nut or flange.

The maximum safe operating speed for the Pferd 60625 (4-1/2 inch) is 13,300 RPM. Always ensure your angle grinder does not exceed this speed rating.

36 grit is considered coarse. It is designed for heavy stock removal, such as grinding down welds or removing heavy rust. It will leave a rougher finish compared to 60, 80, or 120 grit discs.

This disc is optimized for use on Steel and Stainless Steel (INOX). The Zirconia grain is tough enough to handle these hard metals efficiently without premature wear.

Flap discs generally cut cooler, vibrate less, and leave a smoother finish than hard grinding wheels (rocks). They grind and blend in a single step, whereas a grinding wheel is primarily for hogging material and leaves a very rough surface.
