Walter Coolcut XX 6-Inch 120 Grit Resin Fiber Sanding Disc

Get the Job Done Faster with Coolcut XX

As a welder, you know that time spent grinding and sanding is time you aren't welding. That's why the Walter 15X612 Coolcut XX™ 6-inch sanding disc is a game-changer for your tool kit. This isn't your average sandpaper; it's a high-performance abrasive tool designed to eat through metal without bogging down. With a fine 120 grit, this disc is perfect for that final step before you hand off a piece—smoothing out rough grind marks, blending in welds seamlessly, and getting a surface ready for paint or polish. The secret is in the "Cyclone Technology," which is a fancy way of saying this disc bites harder and lasts longer than the cheap stuff.

One of the biggest headaches with sanding aluminum or stainless steel is heat and clogging. Standard discs tend to heat up the metal, causing it to turn blue or warp, and they often gum up (load) with soft aluminum shavings. The Coolcut XX™ is designed to run cooler and resist loading. This means you can keep grinding without stopping every two minutes to swap out a glazed disc. It keeps its bite right down to the backing, giving you a consistent finish every time. If you are working on a custom stainless exhaust or an aluminum boat repair, this disc ensures you don't ruin the temper or the look of the metal.

Comfort matters when you have a grinder in your hand all day. Because these discs cut so aggressively—removing stock up to six times more than standard discs—you don't have to lean into the grinder as hard. This reduces fatigue in your arms and wrists, letting the abrasive do the work for you. The 6-inch size gives you a good balance of surface area coverage and control, making it versatile for both flat surfaces and slightly curved edges. Pair this with a good backing pad, and you'll feel the difference immediately: smoother operation, less vibration, and a finish that makes your work look professional.
