Walter Coolcut XX 6-Inch Ceramic Sanding Disc 36 Grit

Aggressive Grinding for Tough Jobs

When you are staring down a long line of heavy welds that need to be flush, you don't have time for discs that glaze over or stop cutting halfway through the job. The Walter Coolcut XX 6" Sanding Disc is built for welders who need to move metal fast. With a coarse 36 grit, this disc is a workhorse for heavy material removal. Whether you are grinding down a multi-pass MIG weld on structural steel or shaping an aluminum casting, the Coolcut XX bites hard and keeps cutting. The ceramic grain doesn't just rub the surface; it digs in and shaves off metal, saving you arm fatigue and valuable shop time.

We know that working with stainless steel can be a headache if your abrasives run hot. Heat discoloration means more time spent polishing and pickling, which kills your productivity. The "Coolcut" name isn't just marketing—these discs are designed to run cooler than standard zirconia discs. This means you can grind aggressively on stainless tanks, pipes, or sheets without worrying as much about scorching the metal. This feature is equally important for aluminum, where heat buildup can cause the material to melt and clog the disc. The Coolcut XX resists loading, keeping the grain open and effective for longer.

Durability is key in a production environment. Constant disc changes interrupt your flow and drive up consumable costs. Walter has engineered these discs to last. The self-sharpening ceramic grains ensure that the disc cuts just as fast at the end of its life as it did at the start. This 6-inch version gives you that extra reach and surface area compared to standard 4.5-inch or 5-inch grinders, helping you blend larger areas more smoothly. Pair this with a quality backing pad, and you have a setup that is ready to tackle the toughest fabrication challenges in your shop.
