60625 - Pferd Polifan SG Zirkon-Extra 4.5-Inch Zirconia Flap Disc 36 Grit Type 29

Hog Material Faster, Change Discs Less

When you have a stack of parts to grind or a long heavy weld seam to level, you don't want to be walking back to the tool crib every ten minutes for a fresh disc. That is where the Pferd 60625 Polifan SG Zirkon-Extra shines. This isn't your bargain-bin flap disc; it is a heavy-duty workhorse designed for welders who need to move metal fast and keep moving. With a coarse 36 grit, this disc is built for aggressive stock removal—it bites into the metal and rips through weld beads, mill scale, and heavy rust with ease.

The secret sauce here is the Zirconia Alumina grain. Unlike standard grinding wheels that just rub and generate heat, this Zirconia grain stays sharp. It fractures as you grind, constantly exposing fresh cutting edges. This means the disc cuts cool and fast, reducing the risk of heat discoloration on your stainless steel projects. Whether you are working on mild carbon steel or stainless, this disc handles the pressure without bogging down or glazing over. It is the kind of reliability you need when the clock is ticking on a fabrication job.

Pferd calls this the "SG Zirkon-Extra" because they packed it with about 40% more cloth and grain than their standard discs. For you, that means this disc lasts nearly twice as long as the cheaper alternatives. The Type 29 conical shape is angled just right, so when you hold your grinder at a natural angle, you get maximum contact with the work surface. This is perfect for digging into fillets, beveling edges for weld prep, or smoothing out a cap pass. The 7/8-inch arbor fits your standard 4-1/2 inch grinder without any fuss.

Stop wasting time changing out burnt-up discs. The Pferd 60625 gives you the aggression you need for heavy grinding and the longevity to finish the shift. It runs smooth, vibrates less than a hard rock, and leaves a finish that is often good enough to skip a sanding step. If you are serious about your grind, this is the disc to keep in your bag.
