OVERVIEW

Aggressive Weld Removal and Blending

For welders who need a reliable solution for heavy stock removal, the Pferd 60626 Zirconia Flap Disc delivers exceptional results. When you are prepping a joint or grinding down a fresh bead, time is money. This 40 grit abrasive disc is designed to bite into the metal and remove material quickly, helping you move on to the next stage of fabrication faster. Whether you are working with mild steel or stainless steel, the premium Zirconia Alumina grain resists glazing and keeps cutting cool, preventing heat discoloration on your workpiece.

This specific disc is part of Pferd's high-performance line, boasting a "Thick" construction that packs 40% more abrasive flaps onto the backing plate compared to standard economy discs. For the welder, this means fewer trips to the tool crib and less downtime changing out worn discs. The Type 29 conical shape is particularly beneficial for weld grinding; the angled profile allows you to apply more pressure to the weld seam while maintaining control, ensuring a smooth transition from the weld to the base metal without gouging.

Comfort is key during long shifts, and the Pferd 60626 helps mitigate the physical toll of grinding. The layered flap design offers a softer feel than a hard grinding rock, significantly reducing vibration and noise. This smoother operation allows for better control and a superior surface finish, often eliminating the need for subsequent finishing steps. With a standard 7/8" arbor, it fits securely on your 4.5" grinder. Upgrade your abrasive arsenal with a flap disc that works as hard as you do.

FAQ

Type 29 discs are conical (angled), making them best for aggressive stock removal and contouring. Type 27 discs are flat, better suited for blending and finishing on flat surfaces.

While Zirconia can cut aluminum, it is not optimized for it and may clog (load up) quickly. A disc specifically designed for non-ferrous metals is recommended for aluminum.

The 'Thick' designation indicates that the disc contains approximately 40% more abrasive cloth material than standard versions, resulting in a significantly longer service life.

Yes, the Zirconia Alumina grain is excellent for Stainless Steel (INOX) as it cuts cool and resists heat buildup.

This disc has a standard 7/8-inch unthreaded arbor hole.

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.

While always check the label, standard 4-1/2" flap discs are typically rated for around 13,300 RPM.

Zirconia is tougher and self-sharpening, making it more durable and faster-cutting for heavy-duty applications on steel and stainless compared to standard Aluminum Oxide.
