15X528 - Walter Coolcut XX 5-Inch Quick-Change Sanding Disc 80 Grit

High-Performance Zirconia Sanding with Rapid Changeover

The Walter 15X528 Coolcut XX Quick-Change Sanding Disc represents a significant leap in abrasive efficiency for industrial finishing operations. Designed for high-volume fabrication environments, this 5-inch disc utilizes a premium Zirconia Alumina grain structure that delivers aggressive stock removal rates while maintaining a consistent finish. The "XX" designation in the Coolcut line signifies an enhanced formulation tailored for heavy-duty applications where speed and longevity are paramount. By incorporating active cooling agents directly into the bonding matrix, Walter ensures that the disc cuts cool, minimizing the risk of thermal distortion or heat discoloration (bluing) on sensitive substrates like stainless steel and thin-gauge aluminum.

The defining feature of this specific SKU is its Quick-Change (Spin-On) mounting system. Unlike traditional fiber discs that require a locking nut and wrench to replace, the Coolcut XX Quick-Change discs feature an integrated threaded hub. This allows operators to mount and dismount discs by hand in seconds, drastically reducing downtime during multi-step finishing processes. When paired with Walter’s Quick-Change Turbo backing pads, the system provides optimal rigidity and airflow, further extending the life of the abrasive. The 80-grit composition makes this disc an excellent choice for intermediate steps, such as blending weld seams, removing light scale, or preparing surfaces for final polishing.

Engineered for versatility, the 15X528 is compatible with a wide range of ferrous and non-ferrous metals. Whether you are working on structural steel, architectural stainless, or aluminum components, the Coolcut XX delivers a bite that lasts. The 5-inch diameter offers a perfect balance between surface area coverage and maneuverability, allowing access to tighter spaces than larger 7-inch discs while covering more ground than 4.5-inch alternatives. For MRO professionals and fabrication managers seeking to optimize consumable usage and labor hours, this disc offers a compelling return on investment through its durability and ease of use.
