15C502 - Walter Coolcut 5-Inch Resin Fiber Disc 24 Grit

Economical High-Performance Sanding for Steel Fabrication

The Walter 15C502 Coolcut Sanding Disc is a premier choice for industrial fabricators seeking a balance between cost-efficiency and aggressive performance. Engineered by Walter Surface Technologies, the Coolcut line utilizes premium aluminum oxide grains bonded to a heavy-duty vulcanized fiber backing. This specific 5-inch disc features a coarse 24 grit, making it exceptionally suited for heavy stock removal, leveling welds, and breaking down rough surfaces on steel components. The manufacturing process employs an electrostatic grain application method, which orients the abrasive particles for maximum cutting exposure, ensuring a consistent removal rate throughout the life of the disc.

One of the standout features of the Coolcut series is its thermal management. Heat buildup is a common enemy in grinding and sanding applications, often leading to workpiece warping, discoloration (bluing), or premature abrasive failure. Walter has integrated specialized cooling agents into the resin bond of the 15C502, allowing the disc to cut freely and coolly even under significant pressure. This makes it an ideal solution for general-purpose sanding tasks in workshops where throughput and finish quality are paramount. The 7/8-inch arbor fits standard backing pads, ensuring compatibility with most 5-inch angle grinders used in industrial MRO environments.

Durability is central to the design of this fiber disc. The vulcanized backing provides the necessary rigidity to withstand the torque and pressure of heavy grinding while maintaining enough flexibility to contour slightly to the workpiece. Whether you are removing heavy weld seams, deburring flame-cut steel parts, or preparing surfaces for painting, the Walter Coolcut 24 Grit disc delivers reliable, consistent results. It represents a smart investment for shops looking to optimize their abrasive consumable spend without sacrificing the quality of their output.
