Walter Coolcut 5-Inch Resin Fiber Disc 24 Grit

Aggressive Weld Removal with Cool Running Technology

When you are tackling heavy welds and need to remove metal fast, the Walter Coolcut 5" 24 Grit Sanding Disc is your go-to abrasive. Designed for the professional welder who demands speed and consistency, this resin fiber disc cuts through steel with ease. The extra-coarse 24 grit is perfect for the initial stage of finishing, where the goal is to knock down high spots, level heavy welds, and strip away scale or rust quickly. Unlike cheaper alternatives that glaze over or shed grain immediately, the Coolcut disc holds its edge, digging in to remove material efficiently pass after pass.

We know that heat is the enemy of a good finish. Overheating your base metal can cause warping, affect the metallurgical properties of the heat-affected zone, or simply leave ugly heat tints that take extra time to polish out. Walter's Coolcut technology is formulated to mitigate this issue. The specialized bond system helps dissipate heat, keeping the cutting zone cooler. This means you can grind longer and harder without burning the part or the disc. The result is a cleaner surface profile and a longer-lasting disc that doesn't need to be changed every few minutes, keeping you working on the project rather than swapping out consumables.

This disc is built tough with a vulcanized fiber backing that resists tearing and edge chipping. It mounts easily to your 5-inch angle grinder using a standard backing pad and nut. Whether you are working on structural steel, repairing heavy equipment, or doing general fabrication, the 15C502 gives you the bite you need to get the job done right. It is an essential tool for any welder's bag, providing the aggressive performance required for heavy material removal while maintaining the smooth operation Walter abrasives are known for.
