60640 - Pferd POLIFAN PSF Z-EXTRA 6-Inch Flap Disc 40 Grit Type 29

Grind Harder and Longer with Pferd Z-EXTRA

When you have a mountain of welds to grind and deadlines to meet, you need an abrasive that doesn't quit halfway through the job. The Pferd 60640 POLIFAN PSF ZIRKON-EXTRA is built for welders who need aggressive bite and serious durability. This isn't your average flap disc; it is packed with 40% more material than standard discs, meaning you spend more time grinding and less time walking back to the tool crib for a replacement. The 6-inch size gives you plenty of surface area coverage, while the 7/8-inch arbor fits your standard heavy-duty angle grinders.

The 40 grit Zirconia grain is a beast on steel. It is designed to hog off material quickly, whether you are leveling a heavy butt weld, beveling a plate for the next pass, or cleaning up flame-cut edges. Because it is a Type 29 (conical) disc, the flaps are angled just right to dig into the work surface. This shape allows you to apply more pressure for aggressive removal without gouging the metal as easily as a hard rock wheel might. The flaps wear down gradually, exposing fresh grain so the disc keeps cutting fast until it is worn right down to the backing.

Comfort matters when you are behind a grinder all day. The layered flap design of the Pferd 60640 helps absorb vibration, making it smoother to run than a solid grinding wheel. This means less tingling in your hands and arms at the end of the shift. It also runs cooler, reducing the risk of turning your workpiece blue. If you are working with carbon steel and need a disc that balances speed, life, and finish, this Zirconia flap disc is the tool to keep in your bag.
