15X473 - Walter Coolcut XX 4.5-Inch Quick-Change Sanding Disc Grit 36

Advanced Abrasive Technology for High-Production Environments

The Walter Coolcut XX™ Quick-Change Sanding Disc (SKU: 15X473) represents a significant advancement in abrasive technology, specifically engineered to optimize workflow efficiency and material removal rates in industrial environments. This 4.5-inch disc, featuring a coarse 36 grit, is part of the renowned Coolcut XX™ series, which is celebrated for its aggressive cutting capabilities and exceptional longevity. The primary innovation in this specific iteration is the integration of the Quick-Change mounting system. In high-throughput production settings, the time spent changing spent abrasives can accumulate into substantial downtime. The Quick-Change format addresses this bottleneck by allowing operators to mount and dismount discs rapidly without the need for traditional locking nuts or wrenches, provided the appropriate backing pad is utilized.

At the core of the Coolcut XX™ performance is its premium grain structure. Designed for heavy-duty applications, the 36-grit abrasive surface is ideal for rapid stock removal, leveling welds, and removing heavy scale or corrosion. The "Coolcut" designation is not merely a marketing moniker; it refers to the disc's ability to grind with reduced heat generation. This is particularly critical when working with heat-sensitive materials such as stainless steel or thin-gauge aluminum, where thermal discoloration or warping can compromise the integrity of the workpiece. By dissipating heat more effectively than standard aluminum oxide discs, the Coolcut XX™ ensures a cleaner finish and reduces the need for secondary rework.

Furthermore, the structural integrity of the disc is reinforced to withstand the high torque and centrifugal forces associated with angle grinding. When paired with Walter's new Quick-Change Turbo backing pads, the system provides a rigid yet responsive interface between the tool and the work surface. This synergy maximizes the transfer of power, ensuring that the abrasive grains penetrate the material effectively rather than glazing over. The 4.5-inch diameter is the industry standard for versatility, allowing access to tight spaces while still offering a substantial surface area for broader grinding tasks. Whether utilized in metal fabrication, shipbuilding, or general maintenance, this sanding disc offers a superior balance of speed, durability, and ease of use.
