62361 - PFERD POLIFAN SG A-COOL Flap Disc, 4-1/2" x 7/8", 40 Grit, Type 27, Aluminum Oxide

Stop Fighting Clogged Discs on Aluminum

Every welder knows the headache of grinding aluminum. You start with a fresh disc, and within seconds, it's gummed up with soft metal. It stops cutting, starts sliding, and generates a ton of heat. You end up pushing harder, which only makes it worse, or you waste time swapping out discs that should have lasted longer. The PFERD POLIFAN SG A-COOL Flap Disc is built to end that frustration. It is specifically engineered for the metals that give welders the most trouble: aluminum and stainless steel.

The secret is in the "A-COOL" coating. This 40 grit disc doesn't just grind; it actively fights heat and friction. On stainless steel, this means you get a clean cut without the dreaded heat tint or warping that ruins a good weld appearance. On aluminum, the special top-coating prevents the metal from sticking to the grains. Instead of glazing over, the disc sheds the material and keeps biting. You get the aggressive stock removal of a 40 grit wheel without the constant interruptions to clean or change your abrasive.

PFERD also designed this disc with a fiberglass backing instead of plastic. If you've ever had a plastic backing melt and smear black goo all over your nice aluminum finish, you know why this matters. The fiberglass backing wears away cleanly as you use the disc, so you can use every bit of the abrasive without damaging your workpiece. The Type 27 flat shape is perfect for smoothing out long welds or blending surfaces. If you want to get your aluminum or stainless jobs done faster and with less hassle, this is the flap disc you need in your shop.
