15C460 - Walter Coolcut 4.5 Inch 100 Grit Resin Fiber Sanding Disc

Technical Overview of Walter Coolcut 15C460

The Walter 15C460 Coolcut Disc is a premium abrasive solution designed for industrial sanding and finishing applications. Engineered with a diameter of 4-1/2 inches and a fine 100 grit rating, this resin fiber disc is optimized for the final stages of surface preparation where finish quality is paramount. The disc utilizes electrostatically applied abrasive grains, a manufacturing process that ensures uniform grain orientation. This results in a sharp, aggressive cut that remains consistent throughout the life of the disc, providing a superior removal rate compared to standard sanding discs.

Constructed on a high-quality fiber backing, the Coolcut disc offers the rigidity necessary for effective material removal while maintaining enough flexibility to contour slightly to the workpiece. This backing supports the abrasive grain under pressure, preventing premature shedding and ensuring that the disc wears evenly. The 100 grit specification makes it particularly suitable for light weld removal, blending, and general surface cleaning on steel substrates. It effectively smooths out rough surfaces left by coarser abrasives, preparing the metal for painting, coating, or final polishing.

Thermal management is a critical feature of the Coolcut line. The abrasive formulation is designed to cut cool, minimizing heat buildup at the contact point. This is essential when working with heat-sensitive materials or thin-gauge metals where thermal distortion or discoloration (heat tint) is a concern. By reducing friction and heat, the disc not only protects the workpiece but also extends its own service life. The 15C460 is compatible with standard 4-1/2 inch angle grinders equipped with a suitable backing pad, making it a versatile tool for fabrication shops, maintenance departments, and manufacturing facilities requiring reliable, high-performance abrasives.
