OVERVIEW

High-Performance Zirconia Flap Disc for Industrial Steel Applications

The Pferd 60640 POLIFAN PSF ZIRKON-EXTRA Flap Disc represents a significant advancement in abrasive technology for industrial metalworking. Engineered for professionals who demand efficiency and longevity, this 6-inch disc utilizes premium Zirconia Alumina grain, a material renowned for its toughness and self-sharpening characteristics. The "EXTRA" designation in the PSF ZIRKON-EXTRA line indicates a specialized construction featuring a unique flap arrangement and approximately 40% more abrasive material compared to standard PSF discs. This density translates directly to a longer service life, reducing the frequency of disc changes and lowering overall consumable costs in high-volume production environments.

Designed with a Type 29 conical profile, this flap disc is optimized for aggressive stock removal and edge work. The angled geometry allows for greater surface contact at comfortable working angles (typically 15 to 25 degrees), making it superior for contouring and grinding out heavy welds. The 40 grit abrasive is particularly effective for rapid material removal on carbon steel, easily handling tasks such as chamfering, beveling, and leveling weld seams. The robust fiberglass backing plate provides the necessary rigidity for high-pressure grinding while dampening vibration to protect both the machine and the operator.

Pferd's commitment to quality ensures that the 60640 delivers consistent performance from the first spark to the last. The Zirconia grain fractures under pressure to reveal new, sharp cutting edges, maintaining a high cut rate throughout the life of the disc. This self-sharpening action prevents glazing and reduces heat buildup, which is critical for maintaining the structural integrity of the workpiece. For MRO specialists and fabrication managers seeking a reliable, high-endurance abrasive solution for steel applications, the POLIFAN PSF ZIRKON-EXTRA is a proven choice.

  • Surface grinding and blending on carbon steel fabrication.
  • Removing mill scale and heavy rust.
  • Contour grinding on tanks and vessels.

FAQ

Type 29 discs are conical (angled), which makes them better for aggressive stock removal and contour work because they provide better surface contact at steeper angles. Type 27 discs are flat, making them better for blending and finishing on flat surfaces.

While Zirconia can cut aluminum, it is not recommended as the primary choice because soft metals can clog (load) the flap disc quickly. A disc specifically designed for aluminum with a coating to prevent loading would be better.

The 'EXTRA' in POLIFAN PSF ZIRKON-EXTRA indicates that the disc is built with a special flap arrangement and contains approximately 40% more abrasive material than the standard PSF line, offering significantly longer service life.

No, this flap disc comes with an integrated fiberglass backing plate. It mounts directly to the angle grinder using the grinder's retaining nut or flange system.

Always check the label on the specific disc, but generally, 6-inch flap discs are rated for a maximum speed of around 10,200 RPM. Never exceed the rated RPM.

40 grit is a coarse abrasive designed for heavy stock removal and shaping. It will leave a relatively rough scratch pattern. For finishing or blending, you would typically step up to 60, 80, or 120 grit.

The Pferd 60640 is optimized for use on steel and ferrous metals. The Zirconia grain provides excellent cut rates and durability on these hard materials.
