48A031 - Walter Coolcut XX Sanding Disc 4-1/2" x 7/8" 36 Grit

High-Performance Ceramic Sanding Disc

The Walter Coolcut XX sanding disc (SKU: 48A031) represents the pinnacle of fiber disc technology for industrial metalworking. Engineered by Walter Surface Technologies, this 4-1/2 inch disc features a proprietary blend of premium ceramic grains designed to deliver the most aggressive stock removal rates in its class. Unlike standard aluminum oxide discs that dull quickly, the ceramic grains in the Coolcut XX self-sharpen during use, fracturing to reveal fresh cutting edges that maintain high performance throughout the disc's lifespan.

This 36-grit variant is specifically optimized for heavy-duty applications such as grinding down weld seams, beveling thick plates, and removing heavy scale or rust. The disc incorporates Walter's advanced bonding technology which promotes cool cutting, significantly reducing the risk of heat discoloration or warping on sensitive workpieces like stainless steel. With a maximum speed rating of 13,300 RPM, it is compatible with standard angle grinders and requires a suitable backing pad for safe and effective operation.

Industrial professionals choose the Coolcut XX for its efficiency; by removing more material in less time, it reduces labor costs and operator fatigue. Whether working on carbon steel, stainless steel, or aluminum, the 48A031 delivers consistent, aggressive cutting power that stands up to the most demanding fabrication environments.
