15X452 - Walter Coolcut XX 4-1/2 Inch Resin Fiber Sanding Disc, 24 Grit

Advanced Abrasive Technology for Industrial Productivity

The Walter 15X452 Coolcut XX™ Sanding Disc represents the pinnacle of resin fiber disc engineering, designed specifically for high-volume industrial environments where time and material costs are critical. At the core of this 4-1/2 inch disc is Walter's proprietary Cyclone™ Technology, a revolutionary geometric grain arrangement and cooling channel design that fundamentally changes how the abrasive interacts with the workpiece. Unlike traditional sanding discs that often glaze over or generate excessive heat during heavy stock removal, the Coolcut XX maintains a consistent, aggressive cut throughout its lifespan.

With an ultra-coarse 24 grit rating, this disc is engineered for the most demanding applications, including leveling heavy weld seams, removing deep surface imperfections, and rapid stock removal on hard alloys. The specialized ceramic grain blend is optimized for both carbon steel and stainless steel, ensuring versatility across mixed-material fabrication shops. One of the primary challenges in grinding stainless steel is heat generation, which can lead to warping or bluing of the metal. The Coolcut XX addresses this with its active cooling agents and the unique Cyclone spiral pattern, which facilitates superior chip evacuation and airflow at the grinding zone.

Operational efficiency is significantly boosted by the disc's longevity. Field tests and performance metrics indicate that Coolcut XX discs can outlast conventional aluminum oxide discs by a factor of six, and perform material removal at twice the speed. For facility managers and procurement specialists, this translates to reduced inventory turnover, fewer tool changes for operators, and a lower total cost of ownership per finished part. The disc requires a compatible backing pad (typically a Turbo pad) to provide the necessary rigidity and cooling support for maximum performance. By integrating the 15X452 into your abrasive inventory, you are investing in a solution that prioritizes speed, finish consistency, and operator safety through reduced vibration and effort.
