67197 - Pferd POLIFAN-CURVE Flap Disc 5" x 7/8" 60 Grit Zirconia for Steel

The Ultimate Disc for Fillet Welds

Every welder knows the frustration of trying to grind a fillet weld with a standard flat or conical flap disc. You either wear out the edge instantly or dig into the metal where you don't want to. The Pferd POLIFAN-CURVE 5" Flap Disc changes the game. It is built with a special radial shape that literally hugs the corner of the joint. This means you can get right into that 90-degree angle and grind the bead smooth without fighting the tool.

This model (67197) comes in 60 Grit, which is the sweet spot for taking down a steel weld quickly while leaving a finish that looks good enough to paint. The Zirconia grain is tough and self-sharpening, so it doesn't glaze over halfway through the job. Because the flaps wrap around the edge, you get way more use out of a single disc compared to standard pads that just burn up on the perimeter.

If you are fabricating structural steel, frames, or any parts with tight inside corners, this disc is a massive time-saver. It fits your standard 5-inch angle grinder with a 7/8" arbor, so there is no need for special adapters. Just throw it on, and experience how much smoother and faster fillet grinding can be. It cuts cool, vibrates less, and leaves a professional profile every time.
