Walter Coolcut XX 4.5-Inch 80 Grit Sanding Discs (50-Pack)

Experience Superior Control and Speed with Coolcut XX

For professional welders and metal fabricators, the quality of the finish is just as important as the strength of the weld. The Walter 4-1/2" Gr80 Coolcut XX Sanding Discs are designed to give you the edge you need when prepping surfaces or blending welds. This 50-pack of 80-grit discs (SKU: 15X458B) features Walter's breakthrough Cyclone Technology, which isn't just a marketing term—it's a tangible improvement in how the abrasive bites into the metal. You will feel the difference immediately: these discs cut twice as fast as standard sanding discs, allowing you to smooth out beads and refine surfaces with less pressure and less fatigue.

One of the biggest frustrations in metal finishing is a disc that dies halfway through the job. The Coolcut XX series is engineered to last, offering an impressive six times more material removal capacity than generic alternatives. This means fewer trips to the tool cabinet to swap out a worn disc and more time making sparks. The 80-grit texture is perfect for that "middle ground" work—aggressive enough to take down high spots and light weld spatter, yet fine enough to leave a scratch pattern that is easily blended for a paint-ready or polished finish. It excels on a wide range of materials, including tricky aluminum which tends to clog lesser abrasives, as well as tough stainless steel and carbon alloys.

Using the right abrasive can also protect your workpiece. The Coolcut XX discs are designed to cut cool, reducing the risk of warping thin sheet metal or bluing stainless steel due to friction heat. This makes them an essential accessory for custom fabrication shops, automotive restoration, and sanitary welding applications. Compatible with standard 4-1/2 inch angle grinders (requires a backing pad), these discs snap into your existing setup effortlessly. With this bulk pack of 50, you can ensure that you always have a fresh, high-performance disc ready to go, helping you achieve that perfect, professional finish on every project.
