15C455V - Walter Coolcut 4-1/2" Grit 50 Resin Fibre Sanding Discs (5-Pack)

Premium General Purpose Sanding Discs for Steel

The Walter Coolcut 4-1/2" Grit 50 Sanding Discs (SKU: 15C455V) represent a reliable and efficient solution for MRO professionals and fabricators requiring consistent surface finishing on steel. Engineered by Walter Surface Technologies, these resin fibre discs are manufactured using a sophisticated electrostatic process. This technique ensures that the premium aluminum oxide grains are oriented vertically and distributed evenly across the disc surface, maximizing the cutting potential of each grain and ensuring a uniform scratch pattern throughout the disc's lifespan.

One of the defining characteristics of the Coolcut line is its thermal management capability. These discs are designed to promote a cool cutting action, which is critical when working on heat-sensitive applications or when trying to avoid thermal discoloration (blueing) of the workpiece. The 50 grit specification places this disc in the coarse-to-medium range, making it exceptionally versatile for tasks ranging from light weld removal and leveling to aggressive surface cleaning and rust removal. The high-quality fibre backing provides the necessary rigidity to withstand the torque of angle grinders while maintaining enough flexibility to contour slightly to the workpiece.

This specific package (15C455V) contains five discs, making it an ideal inventory choice for maintenance cribs or smaller fabrication stations where bulk quantities are not immediately required. Users must utilize these discs with a compatible backing pad (typically turbo or standard rubber pads) to ensure safety and optimal performance. Whether used for preparing surfaces for painting or blending welds, the Walter Coolcut disc delivers a balance of removal rate and finish quality that industrial users demand.
