Walter Coolcut XX 4.5-Inch 80 Grit Sanding Discs (5-Pack)

Aggressive Cutting Power for Professional Welders

Take your metal finishing to the next level with the Walter Coolcut XX™ 4-1/2" 80 Grit Sanding Discs. As a welder, you know that heat is the enemy when finishing a workpiece, especially on stainless steel where warping and blueing can ruin a perfect job. These discs are specifically designed to combat heat buildup. They feature Walter's exclusive Cyclone Technology—a unique pattern of abrasive grains that acts like a built-in fan, forcing air over the work surface to keep it cool while you grind. This means you can push harder and work faster without worrying about damaging the metal.

The 80 grit ceramic blend is perfect for that stage where you need to blend a weld profile smoothly into the base metal or remove light spatter and mill scale before final finishing. Unlike cheap paper discs that glaze over and stop cutting after a few minutes, the Coolcut XX™ bites into the metal and keeps cutting aggressively until the grain is completely worn. This 5-pack (15X458V) is perfect for your tool bag, ensuring you have fresh, high-performance discs ready when you need them.

Whether you are working on mild steel, stainless, or aluminum, these discs deliver a consistent finish and exceptional longevity. The 4-1/2 inch size fits standard angle grinders, making them a versatile choice for shop work or field repairs. Pair them with a high-quality backing pad to experience the smoothest, coolest sanding action available on the market today.
