15C455 - Walter Coolcut 4.5-Inch Resin Fibre Disc 50 Grit

Industrial-Grade General Purpose Sanding

The Walter 15C455 Coolcut™ Sanding Disc represents a standard of excellence in general-purpose metal finishing. Designed for industrial environments where consistency and longevity are paramount, this 4-1/2 inch resin fibre disc is engineered to deliver reliable performance across a variety of steel applications. At the core of the Coolcut's performance is Walter's proprietary electrostatic distribution process. Unlike standard gravity-fed abrasive manufacturing, this electrostatic method aligns each aluminum oxide grain vertically relative to the backing. This orientation ensures that the sharpest points of the abrasive are always in contact with the workpiece, resulting in a significantly higher removal rate and a more aggressive initial cut compared to conventional discs.

The 50 Grit composition of the 15C455 places it in an ideal position for technicians requiring a balance between material removal and surface preparation. It is aggressive enough to handle light weld removal and surface cleaning tasks effectively, yet fine enough to prepare surfaces for subsequent finishing steps without leaving deep, difficult-to-remove gouges. The disc is built upon a high-quality vulcanized fibre backing, which provides the necessary rigidity to withstand the torque and pressure of angle grinding operations while maintaining enough flexibility to contour slightly to the workpiece.

Thermal management is a critical aspect of abrasive performance, and the Coolcut series addresses this with specialized active agents incorporated into the resin bond. These agents help to dissipate heat generated during friction, creating a "cool cutting" action that protects the substrate from heat-induced discoloration or metallurgical changes. This feature is particularly beneficial when working on thinner gauge steels where warping is a concern. For MRO professionals and fabricators looking for a dependable, cost-effective solution for everyday sanding needs, the Walter Coolcut 15C455 offers a superior service life and consistent finish quality.
