15X452V - Walter Coolcut XX 4.5-Inch Resin Fiber Sanding Disc 24 Grit (5-Pack)

Premium Heavy-Duty Sanding Performance

The Walter Coolcut XX™ sanding disc represents the pinnacle of resin fiber disc technology, designed specifically for industrial environments where speed and efficiency are paramount. This 5-pack of 4-1/2" discs features an aggressive 24 grit, making it the ideal choice for heavy stock removal, leveling welds, and removing deep surface imperfections. Walter Surface Technologies has engineered the Coolcut XX series with a proprietary blend of premium ceramic grains that self-sharpen during use, ensuring that the cutting action remains consistent throughout the life of the disc. Unlike standard aluminum oxide discs that dull quickly, these ceramic discs fracture to reveal new sharp edges, maintaining a high removal rate even under heavy pressure.

One of the standout features of the Coolcut XX line is its thermal management. Heat is the enemy of both the abrasive and the workpiece, often leading to glazing of the disc or discoloration (blueing) of the metal. These discs are formulated with specialized cooling agents that actively reduce surface temperature during the grinding process. This makes them exceptionally well-suited for working with heat-sensitive materials like stainless steel and aluminum, as well as standard carbon steel. The 15X452V pack provides five high-performance discs, offering a convenient quantity for small to medium fabrication jobs or for testing the superior performance of the Coolcut XX line before committing to bulk quantities.

Durability is a core component of the Walter design philosophy. The heavy-duty vulcanized fiber backing provides the rigidity needed to withstand the torque of high-powered angle grinders while offering enough flexibility to contour slightly to the workpiece. When paired with Walter's Turbo backing pads, these discs deliver maximum mechanical advantage, allowing operators to remove more material in less time with less fatigue. Whether you are in a shipyard, a structural steel shop, or a custom fabrication studio, the Coolcut XX 24 grit disc delivers the aggressive bite required for the toughest grinding applications.
