OVERVIEW

Get a Brilliant Finish on Aluminum Projects

Take your aluminum fabrication projects to the next level with the Pferd Polivlies Flap Disc. If you are tired of clogging up standard sanding discs or struggling to get a smooth, consistent finish on soft metals, this is the tool you need. Designed specifically for the unique challenges of grinding aluminum, this 4-1/2 inch disc features a specialized non-woven material that resists loading, meaning it won't gum up with aluminum shavings like traditional sandpaper often does.

This disc is all about the finish. Rated at 240 grit, it is not a hogging tool for removing heavy welds, but rather a finishing tool for blending scratches, cleaning up oxidation, and creating a smooth, professional look. The "Polivlies" flaps are flexible and forgiving, allowing you to work over curves and edges without gouging the metal. It acts almost like a cushion, smoothing out the surface while leaving a brilliant satin finish that looks great on custom car parts, architectural metalwork, or marine repairs.

Heat is the enemy of a good finish, especially on aluminum. The open structure of this Pferd disc keeps things cool, preventing heat marks and discoloration. Whether you are prepping a surface for coating or leaving it as a raw, finished metal, this tool saves you time and elbow grease. Simply mount it to your compatible grinder with a 3/4" arbor and experience the difference a high-quality German-engineered abrasive can make in your shop.

FAQ

Regular flap discs use coated abrasive cloth designed for stock removal and grinding. This Polivlies disc uses a non-woven nylon mesh for surface conditioning, finishing, and polishing without removing significant material.

While it is optimized for aluminum to prevent loading, the abrasive grain can work on steel. However, for steel applications, specific Polivlies discs for steel might offer better longevity.

This specific disc has a 3/4" arbor hole. Please verify your tool's spindle size before purchasing, as standard angle grinders often use 7/8" or 5/8"-11 connections.

240 grit is considered a fine grade. It produces a smooth, satin finish and is excellent for blending fine scratches or preparing a surface for a mirror polish.

The open structure of the non-woven material is specifically designed to resist loading and clogging, which is a common issue with standard abrasives on soft metals like aluminum.

No, this is a flap disc with an integrated backing plate (usually fiberglass), so it mounts directly to the tool without an additional backing pad.

Always check the label on the disc itself, but generally, 4-1/2" non-woven flap discs are rated for around 13,300 RPM, though they often perform best at lower speeds for finishing.

No, this is a finishing tool. You should use a coarse grinding wheel or standard flap disc (e.g., 40 or 60 grit) to remove the weld first, then use this disc to blend and finish the surface.
