Walter Coolcut XX Flap Drum 80 Grit

Erase Welds and Blend Surfaces Fast

For welders who need to turn a rough bead into a smooth, seamless surface, the Walter 48E011 Coolcut XX Flap Drum is an essential weapon in your arsenal. This 80 grit drum is built to chew through metal while leaving a consistent, professional finish. It is designed to fit the Walter Line-Mate and other linear finishers, transforming your machine into a powerhouse for graining and blending.

Why struggle with uneven finishes using standard angle grinders when you can achieve a perfect linear grain with this drum? The 4-inch width covers a wide path, smoothing out ripples and high spots in a fraction of the time. The Zirconia Alumina grain is tough and aggressive, making short work of mild steel, stainless steel, and aluminum. Unlike cheaper abrasives that glaze over or shed grain, the Coolcut XX keeps cutting aggressively thanks to its self-sharpening flaps.

Heat is the enemy of a good finish, especially on stainless. That's why Walter engineered this drum to run cool. You can bear down on the work without worrying about burning the metal or turning it blue. The 5/8"-11 spin-on arbor means you can swap drums in seconds—no wrenches, no hassle. Just spin it on, lock it in, and get back to work.

Whether you are fabricating food-grade stainless equipment, architectural railings, or just cleaning up a repair job, this drum gives you the control and speed you need. It bridges the gap between grinding and polishing, effectively removing 60-grit scratches and leaving a surface that is ready for a final conditioning step or good enough to stand on its own as a matte finish.
