62365 - Pferd POLIFAN Aluminum Flap Disc 5-Inch 40 Grit Type 27

Grind Aluminum Without the Clog

Every welder knows the frustration of taking a grinder to a piece of aluminum. You start with a fresh disc, and within seconds, it looks like a glazed donut—clogged with soft metal, generating heat, and refusing to cut. The Pferd 62365 POLIFAN Flap Disc is the solution to that headache. Designed specifically for aluminum and non-ferrous metals, this disc is built to keep cutting when others would have already ended up in the trash bin. If you work with aluminum trailers, boat hulls, or custom fabrication, this is the consumable that will change your workflow.

Why It Works: The secret lies in the coating. Pferd has engineered this flap disc with special fillers that prevent the soft aluminum chips from sticking to the abrasive grains. This "anti-loading" technology means the 40-grit abrasive stays sharp and exposed, digging into the metal to remove stock fast. Whether you are grinding down a heavy TIG weld or beveling an edge for fit-up, this disc delivers aggressive performance without the heat buildup that warps your material.

Type 27 vs. Type 29: This model is a Type 27, which means it has a flat face. Flat discs are superior for blending and smooth finishing on flat surfaces. While a conical (Type 29) disc is great for aggressive digging, the Type 27 gives you more control when you want to feather a weld into the base metal seamlessly. At 5 inches in diameter, it offers a bit more surface area and life than a standard 4.5-inch disc, helping you get more done between changes.

Built for the Pro: Pferd is a brand synonymous with German quality and safety. These discs are balanced to run smoothly, reducing the vibration that leads to hand fatigue during long shifts. The 40 grit is coarse enough to rip through material quickly but, because it's a flap disc, it leaves a smoother finish than a hard grinding wheel would. Stop wasting money on discs that clog after two minutes. Switch to the Pferd POLIFAN Aluminum line and experience the difference a purpose-built tool makes.
