15X603 - Walter Coolcut XX 6-Inch Ceramic Sanding Disc 36 Grit

Advanced Ceramic Abrasive Technology

The Walter Coolcut XX 6" Sanding Disc (SKU: 15X603) represents the pinnacle of resin fiber disc technology, engineered specifically for industrial environments where speed and efficiency are paramount. At the core of the Coolcut XX series is a premium ceramic grain structure. Unlike traditional abrasive grains that dull and round over time, these ceramic grains are designed to micro-fracture under pressure. This self-sharpening mechanism continuously exposes new, sharp cutting edges, ensuring that the disc maintains a consistent and aggressive removal rate throughout its entire lifespan.

This 36-grit variant is optimized for heavy stock removal applications. The coarse grit allows for rapid material displacement, making it an essential tool for leveling welds, removing heavy scale, and shaping metal components. The 6-inch diameter offers a balanced compromise between coverage area and maneuverability, suitable for both large surface blending and targeted grinding tasks. The disc is manufactured with a robust fiber backing that provides the necessary rigidity to withstand high contact pressures without tearing or deforming, ensuring safety and reliability during intensive operations.

One of the critical technical advantages of the Coolcut XX is its thermal management. Grinding friction generates significant heat, which can be detrimental to metallurgical properties, particularly in stainless steel and exotic alloys. The Coolcut XX formulation includes active grinding agents that lubricate the contact zone, significantly reducing heat generation. This "cool cut" capability minimizes the risk of heat tinting (blueing) and warping, thereby preserving the integrity of the workpiece and reducing the need for secondary rework processes. It is compatible with standard backing pads, though performance is maximized when paired with high-performance turbo pads that facilitate airflow and cooling.
