Walter Coolcut 4.5-Inch Resin Fibre Sanding Disc 24 Grit (5-Pack)

Aggressive Weld Removal and Leveling

For professional welders requiring rapid material removal without compromising the integrity of the base metal, the Walter Coolcut™ 4-1/2" Sanding Disc is an essential tool. This 5-pack of 24-grit discs (15C452V) is designed to tackle the toughest grinding tasks, from hogging down heavy weld seams to beveling plate edges for penetration. The coarse 24 grit structure provides an aggressive bite, allowing operators to remove metal quickly and efficiently, reducing overall labor time on fabrication projects.

One of the primary challenges in aggressive grinding is heat management. Walter has addressed this with their proprietary Coolcut technology, which integrates cooling agents directly into the disc's bonding matrix. This results in a cooler grind that minimizes the risk of warping thin gauge metals or bluing stainless steel. The discs mount easily to standard 4-1/2 inch angle grinders equipped with a suitable backing pad (typically turbo or smooth rubber pads depending on the desired flexibility). Whether you are prepping a surface for welding or finishing a rough structural joint, these discs provide the durability and cut rate needed for heavy-duty industrial use.

Application Focus

• Heavy Stock Removal: Ideal for grinding down excess weld metal and spatter.
• Surface Prep: Quickly strips rust, paint, and mill scale to expose clean metal.
• Multi-Material Use: Effective on carbon steel, cast iron, and aluminum alloys.
