15X508 - Walter Coolcut XX 5" x 7/8" 80 Grit Sanding Disc (25-Pack)

Aggressive Grinding, Cool Finish: Walter Coolcut XX 5" Discs

For welders who demand speed without sacrificing quality, the Walter Coolcut XX 5" Sanding Disc (80 Grit) is the ultimate tool for your angle grinder. Whether you are blending welds on a custom stainless steel exhaust or smoothing out aluminum fabrication, these discs are built to perform. The "XX" in the name stands for extreme performance, delivering up to double the cutting speed of standard fiber discs. This means you spend less time grinding and more time welding, helping you finish jobs faster and with less fatigue.

Heat is the enemy of a good finish, especially on stainless steel. Walter has solved this problem by incorporating exclusive cooling agents directly into the abrasive matrix. As you grind, these agents activate to lubricate the surface and dissipate heat, preventing the dreaded "blueing" or discoloration that can ruin the look of a finished piece. This feature makes the 15X508 particularly valuable for architectural metalwork, food-grade stainless applications, and aluminum boat repairs where surface appearance is paramount.

This 25-pack of 80 grit discs ensures you have plenty of supply for the long haul. The 80 grit rating offers a versatile medium finish—aggressive enough to take down small welds and spatter, yet fine enough to prepare surfaces for painting or further polishing. Designed to fit standard 5-inch grinders with a 7/8" arbor (using a backing pad), these discs are a staple for any serious welder's toolbox. Experience the difference that premium abrasives make in your daily workflow.
