48A022 - Walter Coolcut XX 2-Inch Sanding Disc 36 Grit Spin-On

High-Performance Abrasive for Aggressive Stock Removal

The Walter Surface Technologies Coolcut XX Sanding Disc (SKU: 48-A-022) is a premium abrasive solution designed for industrial environments requiring efficiency and precision. Engineered with high-quality abrasive grains, this 2-inch disc is specifically formulated to deliver an extremely high removal rate while maintaining a cool cutting action. This thermal management is critical when working on heat-sensitive materials, as it significantly reduces the risk of warping, discoloration, or glazing of the workpiece.

The 36-grit composition makes this disc an aggressive tool, ideal for heavy-duty applications such as leveling welds, removing heavy corrosion, and shaping metal surfaces. Its compact 2-inch diameter allows operators to access tight corners, contours, and confined spaces that larger grinding wheels cannot reach. The disc features Walter's Spin-On fastening system, which is compatible with standard quick-change backing pads (similar to Type R systems). This design ensures that disc changes are instantaneous, minimizing downtime and keeping production lines moving efficiently.

Durability is a hallmark of the Coolcut XX series. The robust backing material supports the abrasive grain under high pressure, preventing premature tearing or edge wear. With a maximum speed rating of 30,000 RPM, this disc is optimized for use with high-speed pneumatic or electric die grinders. Whether used in automotive fabrication, aerospace maintenance, or general metalworking, the 48-A-022 provides consistent, reliable performance that meets the rigorous demands of MRO professionals.
