OVERVIEW

Achieve Flawless Finishes with Coolcut XX

For professional welders and fabricators, the finishing stage is where the quality of the work is truly revealed. The Walter Coolcut XX 5" Sanding Disc in 120 Grit (15X512V) is your go-to solution for dialing in that perfect finish on stainless steel and steel projects. Whether you are blending out TIG welds, removing heat tint, or prepping a surface for a final coat, these discs provide the control and consistency you need. This convenient 5-pack is perfect for your toolbox, ensuring you have fresh, high-quality abrasives ready when the job demands a smooth touch.

We know that time is money in the shop. Constant disc changes kill momentum. That's why the Coolcut XX features premium Zirconia grain that stays sharp longer than cheap generic pads. The 120 grit is fine enough to leave a smooth, scratch-free surface but aggressive enough to clean up light imperfections quickly. One of the biggest headaches when finishing stainless steel is warping or discoloration caused by heat. Walter's Coolcut technology is designed to run cooler, protecting your base metal and saving you from having to spend extra time pickling or polishing out heat marks.

Using these discs is straightforward. Mount them on your 5-inch angle grinder with a proper backing pad, and you are ready to go. The 7/8" arbor is the industry standard, so fitment is never an issue. The 5-inch size gives you a bit more surface area than a 4.5-inch disc, which helps in keeping the grinder flat and avoiding gouges. Whether you are building custom railings, repairing food-grade equipment, or doing general automotive fabrication, the Coolcut XX 120 grit disc gives you the professional edge you expect from Walter products.

Don't let a poor finish ruin a great weld. Upgrade your abrasive game with the 15X512V pack. These discs bite hard, run cool, and last long, letting you focus on the craftsmanship rather than fighting with your tools. It's the kind of reliability that makes Walter a favorite brand among serious metalworkers.
