The Walter Surface Technologies Coolcut XX™ Sanding Disc (SKU: 48H328) represents the pinnacle of productivity for small-diameter grinding and finishing applications. Engineered with a premium Zirconia Alumina grain structure, this 3-inch disc is designed to deliver an exceptionally high removal rate while maintaining the structural integrity of the abrasive grains over an extended lifespan. The 80-grit composition makes it an ideal choice for intermediate finishing, blending welds, and removing moderate imperfections without gouging the base material.
One of the defining technical characteristics of the Coolcut XX series is its ability to mitigate thermal transfer. Excessive heat during grinding can lead to work-hardening or discoloration (bluing) of stainless steel and other heat-sensitive alloys. Walter has formulated these discs with active cooling agents that lubricate the cutting surface, ensuring a cooler cut even under heavy pressure. This feature is critical for MRO professionals and fabricators working on high-value components where surface integrity is paramount.
The disc utilizes Walter's proprietary Spin-On mounting system, which is mechanically compatible with industry-standard Type R (plastic button) backing pads. This quick-change mechanism allows operators to switch between grits or product types in seconds, significantly reducing downtime during multi-step finishing processes. Rated for a maximum speed of 20,000 RPM, the 48H328 is optimized for use with high-speed die grinders, providing stable and vibration-free operation that reduces operator fatigue.
