15C454 - Walter Coolcut 4.5 Inch 40 Grit Resin Fiber Sanding Disc

Reliable General Purpose Sanding for Industrial Applications

The Walter Coolcut 4-1/2" Grit 40 Sanding Disc (SKU: 15C454) is a staple abrasive for fabrication shops and industrial maintenance teams requiring consistent performance on steel. Engineered by Walter Surface Technologies, the Coolcut line is designed to deliver a balance of aggressive removal rates and long service life, making it an economical choice for high-volume sanding tasks. This specific disc features a coarse 40 grit, making it the ideal tool for heavy stock removal, leveling welds, and stripping tough scale or rust from metal surfaces.

What sets the Coolcut disc apart is Walter's advanced manufacturing process. The discs utilize a specialized electrostatic application method that orients the aluminum oxide grains vertically. This ensures that the sharpest cutting edges are always exposed to the workpiece, maximizing the cut rate from the very first pass. The abrasive grains are bonded to a premium vulcanized fibre backing, which provides the necessary rigidity to withstand high pressure while maintaining enough flexibility to contour slightly to the surface. This robust construction prevents the disc from tearing or deforming under the stress of heavy grinding, ensuring safety and reliability in demanding environments.

For industrial supply managers and procurement specialists, the Walter Coolcut represents a dependable inventory item that covers a wide range of general-purpose applications. Whether your team is prepping surfaces for painting, removing weld spatter, or blending metal joints, this disc performs reliably without generating excessive heat. The "Coolcut" name refers to its ability to grind without causing severe heat buildup, which helps prevent heat discoloration and warping on thinner steel sections. Compatible with standard 4-1/2" angle grinders equipped with a suitable backing pad, this disc is a versatile workhorse for any metalworking facility.

Key Industrial Benefits:

• Cost-Effective Performance: Delivers excellent removal rates at a competitive price point.
