15X453V - Walter Coolcut XX 4.5-Inch Grit 36 Resin Fiber Sanding Discs (5-Pack)

High-Performance Abrasive for Industrial Applications

The Walter Coolcut XX Sanding Disc (SKU: 15X453V) represents the pinnacle of resin fiber disc technology, designed specifically for industrial environments requiring aggressive stock removal and extended product life. This 5-pack configuration provides a targeted solution for maintenance, repair, and fabrication professionals who demand consistency and performance. Engineered with a proprietary blend of premium ceramic grains, the Coolcut XX series excels in heavy-duty applications where speed and efficiency are paramount.

One of the critical challenges in abrasive grinding is heat management. Excessive heat can lead to thermal deformation, discoloration (blueing), and structural changes in the base metal. Walter has addressed this with their advanced Coolcut technology, which incorporates active cooling agents directly into the bond matrix. This feature significantly reduces surface temperature during operation, making these discs particularly suitable for heat-sensitive materials like stainless steel and thin-gauge aluminum, while still performing exceptionally well on carbon steel.

The 36 grit specification of this disc indicates a coarse abrasive structure, optimized for the rapid removal of weld seams, heavy mill scale, and deep surface imperfections. The 4-1/2 inch diameter combined with a standard 7/8 inch arbor ensures compatibility with a vast array of industrial angle grinders. To maximize safety and performance, these discs should be used with a compatible turbo or standard backing pad that supports the disc across its surface area. The reinforced fiber backing provides the necessary rigidity to withstand high contact pressures, ensuring the disc maintains its integrity even under the most demanding torque conditions.

In MRO (Maintenance, Repair, and Operations) settings, the longevity of an abrasive is directly tied to cost savings. The Coolcut XX discs are formulated to resist glazing and loading, ensuring that the abrasive grains remain sharp throughout the life of the disc. This self-sharpening action reduces downtime associated with frequent disc changes and increases overall operator productivity. Whether used for beveling prior to welding or leveling a finished weld, the 15X453V delivers reliable, professional-grade results.
