15X508V - Walter Coolcut XX 5-Inch Resin Fibre Sanding Disc 80 Grit (5-Pack)

High-Performance Surface Finishing with Walter Coolcut XX

The Walter Coolcut XX 5" Sanding Disc (SKU: 15X508V) represents the pinnacle of resin fibre disc technology, designed specifically for industrial professionals who demand speed, consistency, and quality. This pack of 5 discs, featuring an 80 grit abrasive, is perfectly suited for intermediate finishing tasks, weld blending, and surface preparation where a balance between stock removal and surface finish is required. The Coolcut XX line is renowned for its ability to remove material aggressively while maintaining a cool operating temperature, a critical feature when working with heat-sensitive materials like stainless steel and thin-gauge aluminum.

At the core of the Coolcut XX performance is a proprietary blend of ceramic and premium abrasive grains. Unlike standard aluminum oxide discs that dull quickly and generate excessive heat, these ceramic grains are engineered to micro-fracture under pressure. This self-sharpening mechanism ensures that fresh, sharp cutting edges are constantly exposed to the workpiece, maintaining a high cut rate throughout the entire lifespan of the disc. For fabricators, this translates to less downtime spent changing discs and reduced operator fatigue, as less pressure is required to achieve the desired result.

These 5-inch discs are designed to mount onto standard angle grinders using a compatible backing pad (typically with a 7/8" arbor). The 80 grit specification makes them an excellent choice for the second step in a finishing process, effectively removing scratches left by coarser 36 or 60 grit discs, or for light stock removal applications where a smoother finish is desired immediately. Whether you are smoothing out a weld seam in a fabrication shop or prepping a metal surface for coating in a maintenance facility, the Walter 15X508V delivers reliable, professional-grade results every time.
