OVERVIEW

Aggressive Grinding Power with Pferd POLIFAN

When you have heavy welds to level and tough steel to grind, you need an abrasive that bites back. The Pferd POLIFAN 5-inch Flap Disc (40 Grit) is built for the welder who demands performance. This isn't your average hardware store disc; it's a professional-grade tool designed to eat through steel rapidly, saving you time and effort on every job.

The secret lies in the Zirconia Alumina grain. This high-tech abrasive material is tougher and sharper than standard grains, meaning it cuts cooler and lasts longer. The 40 grit rating indicates a coarse texture, perfect for the heavy lifting—stripping rust, grinding down thick weld beads, and shaping metal edges. Because it's a Type 29 (conical) disc, it's shaped to fit the natural angle of your grinder, allowing you to apply more pressure for maximum bite without gouging the workpiece unnecessarily.

Pferd has formulated this "Steel Superior" disc to resist loading, so it keeps cutting even under heavy stress. Whether you are working on structural steel, pipe fitting, or general fabrication, this flap disc delivers a consistent finish and reliable durability. Stop wasting time changing out cheap discs that wear out in minutes. Upgrade to Pferd POLIFAN and experience the difference superior German engineering makes in your daily grind.

Key Benefits for Welders

  • Fast Cut Rate: Zirconia grain rips through steel quickly.
  • Long Life: Durable backing and bonding mean fewer disc changes.
  • Versatile: Great for edge grinding and surface blending.
  • Standard Fit: 7/8" arbor fits most 5" angle grinders.

FAQ

Type 27 discs are flat and best for blending and finishing on flat surfaces. Type 29 discs, like this one, are conical (angled), which allows for more aggressive stock removal and better ergonomics when grinding at an angle of 15 to 25 degrees.

While Zirconia can cut aluminum, this specific "Steel Superior" disc is optimized for ferrous metals. Using it on aluminum may cause the disc to "load up" or clog quickly. We recommend discs specifically designed for non-ferrous metals for aluminum work.

Grit refers to the coarseness of the abrasive particles. 40 grit is very coarse, making it ideal for heavy stock removal, grinding down welds, and shaping metal. It leaves a rougher finish than higher grits like 60 or 80.

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

Zirconia Alumina is a tougher, more durable grain that fractures to self-sharpen. It withstands high heat and pressure better than Aluminum Oxide, making it superior for grinding steel and stainless steel.

No, flap discs have a built-in backing plate (in this case, fiberglass). You do not need a separate rubber backing pad like you would for resin fiber discs.

This disc is best suited for working on carbon steel, specifically for tasks requiring high stock removal such as grinding fillet welds, chamfering edges, and removing heavy burrs.
