62363 - PFERD POLIFAN A-COOL SG Flap Disc, 4-1/2" x 7/8", 60 Grit, Type 27, Aluminum & INOX

Stop Clogging Your Discs on Aluminum

Every welder knows the frustration of grinding aluminum: you start working, and within seconds, your flap disc is gummed up with soft metal, turning it into a useless spinning coaster. The PFERD POLIFAN A-COOL SG (SKU: 62363) is designed specifically to fix this problem. With a special top-coating that resists loading, this 60-grit disc keeps cutting where others fail, saving you money on wasted abrasives and time on changeovers.

This 4-1/2" x 7/8" Type 27 disc isn't just for aluminum; it's also a beast on stainless steel. The "A-COOL" formula includes active coolants that keep the temperature down while you grind. This means less warping on thin sheets and less of that rainbow heat tint you have to polish out later. The 60 grit is a perfect middle-ground, aggressive enough to knock down a weld bead but fine enough to leave a smooth finish that's easy to blend.

The backing pad is made of fiberglass, which is strong and safe. If you accidentally grind down to the backing, it won't melt or smear plastic all over your clean metal like some cheaper discs do. Whether you are building aluminum boat hulls, fixing a trailer, or fabricating stainless kitchen equipment, this PFERD disc helps you get a professional finish faster and with less hassle.
