48L342 - Walter COOLCUT XX Sanding Disc 4-1/2" x 7/8" Grit 36

High-Performance Abrasive for Aggressive Material Removal

The Walter COOLCUT XX Sanding Disc (48L342) is engineered for industrial professionals who demand speed, efficiency, and longevity in their abrasive consumables. This 4-1/2 inch disc features a coarse 36 grit composition, making it ideal for heavy stock removal, weld leveling, and surface preparation on tough metals. What sets the COOLCUT XX apart is Walter's proprietary Cyclone Technology. The disc surface is molded with a geometric spiral rib pattern that generates a cooling airflow during rotation, similar to a fan. This innovative design actively dissipates heat, preventing the workpiece from overheating and reducing the risk of thermal distortion or discoloration.

Constructed with premium aluminum oxide grains bonded to a durable fiber backing, the 48L342 delivers consistent cutting performance throughout its lifespan. The specialized cooling channels not only protect the metal surface but also prevent the abrasive grains from glazing over, ensuring that the disc remains sharp and aggressive for longer periods. With a maximum speed rating of 13,300 RPM and a standard 7/8-inch arbor, this disc is compatible with most industrial angle grinders. Whether you are working with carbon steel, stainless steel, or aluminum, the Walter COOLCUT XX provides the aggressive bite needed for demanding fabrication tasks while maintaining a cooler grinding zone than conventional fiber discs.
