OVERVIEW

Premium Abrasive Performance for Industrial Finishing

The Walter Surface Technologies 48R455 Coolcut XX Sanding Disc is a high-performance resin fiber disc designed for versatility and efficiency in industrial environments. Engineered with premium Aluminum Oxide grains, this 4-1/2 inch disc delivers a consistent cut rate and exceptional durability. The 50 grit rating makes it an excellent choice for medium-to-heavy stock removal, bridging the gap between aggressive grinding and surface preparation.

One of the standout features of the Coolcut XX line is its incorporation of active cooling agents directly into the bonding matrix. This technology helps dissipate heat generated during friction, significantly reducing the risk of thermal damage, glazing, or discoloration on the workpiece. This makes the 48R455 particularly effective on heat-sensitive materials such as stainless steel and aluminum, while still performing robustly on carbon steel.

Designed for use with angle grinders, this disc requires a compatible backing pad (typically a Turbo or standard rubber pad) to ensure safety and optimal performance. The 7/8-inch arbor fits standard industrial grinders. Whether you are removing rust, blending welds, or preparing surfaces for painting, the Walter Coolcut XX provides a reliable, long-lasting solution that minimizes downtime and maximizes productivity.
