48A053 - Walter Coolcut XX 7-Inch Sanding Disc Grit 50

Extreme Performance for Heavy Duty Sanding

The Walter Coolcut XX™ Sanding Disc (48-A-053) represents the pinnacle of abrasive technology for industrial metalworking. Designed for professionals who demand speed and efficiency, this 7-inch disc features a coarse 50 grit rating, making it ideal for aggressive stock removal, weld leveling, and heavy surface preparation. At the core of the Coolcut XX performance is Walter's exclusive Cyclone Technology™, a proprietary blend of premium ceramic grains and high-grade aluminum oxide. This unique formulation allows the disc to cut faster and last significantly longer than conventional sanding discs, reducing downtime for disc changes and increasing overall productivity.

One of the standout features of this disc is its ability to grind cool. Heat generation is a common enemy in metal fabrication, often leading to warping or discoloration (heat tint) on sensitive materials like stainless steel. The Coolcut XX is engineered with active grinding agents that lubricate the cutting surface, dissipating heat effectively. This makes it a versatile choice for a wide range of materials, including carbon steel, stainless steel, and aluminum. Whether you are removing heavy welds in a shipyard or blending surfaces in a fabrication shop, this disc provides the consistency required for high-quality results.

Durability is key in industrial environments, and the Walter 48A053 delivers with a robust vulcanized fiber backing that resists tearing and edge chipping. The 7/8-inch arbor hole ensures compatibility with standard backing pads on 7-inch angle grinders. By maintaining a consistent cut rate throughout its lifespan, the Coolcut XX helps operators maintain rhythm and reduce fatigue, as less pressure is needed to achieve the desired removal rate.

Key Applications

• Weld Removal: Rapidly grinds down heavy weld seams on structural steel and piping.


• Surface Leveling: Flattens imperfections and mill scale efficiently.


• Beveling: Prepares edges for welding with precision and speed.


• Blending: Smooths out rough surfaces on stainless steel tanks and vessels.
