OVERVIEW

Aggressive Weld Removal for Professional Fabricators

When you are under the hood and need to grind down a heavy weld bead fast, the Pferd 62222 40 Grit Flap Disc is your go-to consumable. Designed for the rigors of the welding shop, this disc combines the aggression of a grinding wheel with the finish of a fiber disc, allowing you to complete jobs faster and with better results. If you are tired of flap discs that wear out after a few minutes or stop cutting halfway through a job, the Pferd POLIFAN SG series is the upgrade your angle grinder needs.

This 4-1/2 inch disc fits all standard angle grinders with a 7/8 inch arbor. The 40 grit Zirconia Alumina abrasive is a workhorse for heavy stock removal. Whether you are grinding down a multipass fillet weld, prepping a bevel for a butt joint, or removing heavy mill scale, this disc bites into the metal and keeps cutting. The Type 29 conical shape is built for the way welders actually work—allowing you to attack the metal at a steeper angle for more pressure and faster removal without flattening the flaps prematurely.

Pferd has formulated the bond on this disc specifically for steel. This means it won't load up or glaze over when you lean into it. It runs smooth and true, reducing the vibration that leads to "white finger" and fatigue at the end of a long shift. For fabricators who value their time and need reliable performance, the Pferd 62222 delivers professional-grade results on every trigger pull. It bridges the gap between a hard rock and a finishing disc, often allowing you to skip steps and get to the painting or coating stage sooner.

Why Welders Choose This Disc:

  • Fast Weld Leveling: Eats through steel welds quickly, saving you time on cleanup.
  • Consistent Cut: The self-sharpening grain means it cuts just as well at the end of its life as it does at the start.
  • Built Tough: Strong fiberglass backing holds up to the heat and stress of daily fabrication work.

FAQ

Type 29 discs are conical (angled), which provides better surface contact for contour and edge work at steeper angles (15-25 degrees). Type 27 discs are flat, making them better for blending and finishing on flat surfaces at lower angles (0-15 degrees).

While it can physically grind aluminum, it is not recommended. This disc is optimized for steel. Aluminum is soft and will clog (load) the abrasive quickly. For aluminum, use a flap disc specifically designed with a coating to prevent loading.

Zirconia Alumina is a high-performance synthetic abrasive grain that is tougher and more durable than standard aluminum oxide. It is self-sharpening, meaning the grains fracture to reveal new sharp edges, providing a faster cut and longer life.

The maximum operating speed for the Pferd 62222 is 13,300 RPM. Always ensure your angle grinder does not exceed this speed rating for safety.

This specific 'Steel' version is optimized for carbon steel. While it can grind stainless, Pferd manufactures 'INOX' specific discs that run cooler and are contaminant-free to prevent corrosion issues on stainless steel.

No, this flap disc comes with an integrated fiberglass backing plate. It mounts directly to the angle grinder using the standard flange nut or a quick-change nut.

40 grit is a coarse abrasive grade. It is best used for heavy stock removal, such as grinding down large weld beads, removing deep pits, or heavy edge chamfering. It leaves a rougher finish than 60 or 80 grit.

This disc has a 7/8-inch (22.23mm) arbor hole, which is the industry standard for 4-1/2 inch, 5-inch, and 7-inch angle grinders.
