15X456V - Walter Coolcut XX 4.5-Inch 60 Grit Resin Fiber Discs (5-Pack)

Premium Ceramic Blending for Industrial Applications

The Walter Coolcut XX™ 4-1/2" Sanding Disc (SKU: 15X456V) represents the pinnacle of resin fiber disc technology, designed specifically for high-performance industrial environments. Engineered by Walter Surface Technologies, these discs utilize a proprietary blend of premium ceramic abrasive grains that self-sharpen during use. This advanced grain structure ensures that the disc maintains an aggressive cutting rate throughout its entire lifespan, significantly outperforming conventional aluminum oxide or zirconia discs. The 60 grit configuration is optimized for intermediate stock removal, making it an excellent choice for leveling welds, removing heavy mill scale, and preparing surfaces for final finishing steps.

One of the critical challenges in grinding stainless steel and other heat-sensitive alloys is thermal management. Excessive heat can lead to warping, blue discoloration, and changes in the metallurgical properties of the workpiece. The Coolcut XX™ addresses this with specialized active cooling agents bonded directly into the abrasive matrix. These agents lubricate the contact zone and dissipate heat rapidly, ensuring a "cool cut" even under heavy pressure. This feature not only protects the integrity of the metal but also extends the life of the disc by preventing glazing and premature grain shedding.

Durability is further enhanced by the heavy-duty vulcanized fiber backing, which provides the necessary rigidity for high-pressure grinding while retaining enough flexibility to contour slightly to the workpiece. This 5-pack configuration is ideal for maintenance shops, fabrication floors, and tool cribs requiring consistent inventory of high-quality consumables. Compatible with standard 4-1/2" angle grinders using a backing pad and nut assembly, the Walter Coolcut XX™ delivers reliable, professional results for the most demanding metalworking tasks.

Technical Specifications & Performance

The 15X456V discs are rated for a maximum speed of 13,300 RPM, ensuring compatibility with standard industrial angle grinders. The 7/8" arbor hole is the industry standard, allowing for easy mounting on virtually any backing pad system (such as Walter's Turbo or Coolcut pads). By choosing the Coolcut XX series, operators can expect reduced downtime due to fewer disc changes and improved throughput due to faster material removal rates.
