48A030 - Walter Coolcut XX Sanding Disc 4-1/2" Grit 30

High-Performance Stock Removal with Walter Coolcut XX

The Walter Coolcut XX™ Sanding Disc (SKU: 48-A-030) is engineered for industrial professionals who demand efficiency and longevity in their abrasive consumables. Designed with a premium blend of Zirconia Alumina grains, this 4-1/2 inch resin fiber disc delivers an exceptionally aggressive cut rate, making it the ideal choice for heavy stock removal tasks such as leveling welds, removing mill scale, and beveling edges.

One of the critical challenges in metal fabrication is heat generation, which can lead to workpiece discoloration or warping. The Coolcut XX addresses this with its specialized grain structure and bonding agents that promote cool cutting action. This feature not only protects the base material—whether it be carbon steel, stainless steel, or aluminum—but also prevents the disc from glazing over, thereby extending its usable life. The 30 grit specification ensures deep bite and rapid material evacuation, significantly reducing the time required for rough grinding stages.

Durability is central to the design of the 48-A-030. The disc features a reinforced fiber backing that withstands the high torque and pressure of modern angle grinders running up to 13,300 RPM. This structural integrity ensures safety and consistent performance throughout the disc's lifespan. For optimal results, this disc should be used in conjunction with a high-quality turbo backing pad, which helps to dissipate heat and maximize the contact area of the abrasive grains.

In MRO and fabrication environments where productivity is paramount, the Walter Coolcut XX stands out as a reliable solution. Its ability to maintain a high cut rate without frequent replacements translates to lower total abrasive costs and higher throughput for welding and fabrication operations.
