15X505V - Walter Coolcut XX 5-Inch Ceramic Sanding Disc 50 Grit (5-Pack)

High-Performance Ceramic Abrasive for Industrial Fabrication

The Walter Coolcut XX 5-inch sanding disc (SKU 15X505V) represents the pinnacle of resin fiber disc technology, engineered specifically for industrial environments requiring maximum stock removal rates and extended abrasive life. This product utilizes premium ceramic grain technology, which is distinct from standard aluminum oxide or zirconia grains due to its micro-crystalline structure. As the disc is used, the ceramic grains fracture in a controlled manner, continuously exposing new, sharp cutting edges. This self-sharpening mechanism ensures that the removal rate remains consistent throughout the lifespan of the disc, rather than dropping off significantly as the abrasive wears.

With a coarse 50 grit rating, this disc is positioned as an aggressive solution for heavy-duty applications such as leveling weld seams, removing heavy mill scale, and shaping metal profiles. It is particularly effective on hard materials like stainless steel and various carbon steel alloys. The "Coolcut" designation refers to the disc's ability to dissipate heat effectively, often aided by active grinding agents in the top coat that reduce friction. This is critical when working with heat-sensitive alloys to prevent thermal discoloration or warping of the workpiece.

For optimal performance, this disc should be paired with a high-quality backing pad, such as Walter's Turbo backing pads, which provide the necessary rigidity and airflow to maximize the ceramic grain's cutting potential. The 5-inch diameter offers a balance between surface area coverage and maneuverability, making it a versatile choice for both flat surfaces and curved fabrications. This pack contains 5 discs, ensuring a ready supply for production runs. Industrial operators will appreciate the reduced downtime associated with fewer disc changes and the ergonomic benefit of applying less pressure to achieve superior cutting results.
