15X726 - Walter Coolcut XX 7-Inch Spin-On Sanding Disc Grit 60

High-Performance Abrasive Technology for Industrial Applications

The Walter 15X726 Coolcut XX™ Sanding Disc represents the pinnacle of abrasive engineering for heavy-duty industrial environments. Designed with a 7-inch diameter and a coarse 60 grit, this disc is engineered to tackle the most demanding stock removal and blending tasks found in metal fabrication, shipyards, and structural steel workshops. The Coolcut XX™ series is distinguished by its proprietary abrasive formulation, which combines aggressive cutting grains with active cooling agents. This unique composition ensures that the disc cuts faster and lasts longer than conventional sanding discs, significantly reducing the total cost of operation by minimizing downtime associated with frequent disc changes.

One of the critical technical advantages of the 15X726 is its integration with the Quick-Change (Spin-On) mounting system. In high-volume production settings, the time spent swapping out worn abrasives can accumulate into substantial lost productivity. The Quick-Change system eliminates the need for locking nuts and wrenches; the operator simply spins the old disc off and spins the new one on, centering it perfectly every time. This positive drive system also ensures maximum torque transfer from the tool to the workpiece, preventing slippage even under heavy load.

Thermal management is a key factor in abrasive performance, particularly when working with stainless steel and aluminum. Excessive heat can lead to glazing of the disc, work hardening of the material, or heat tinting that requires secondary cleanup. The Coolcut XX™ disc is designed to be paired with Walter’s Quick-Change Turbo backing pads. These pads feature ribbed designs that create a cyclonic airflow effect behind the disc, dissipating heat rapidly. Combined with the disc's internal cooling agents, this system allows for aggressive grinding without compromising the metallurgical integrity of the workpiece. Whether leveling welds, removing mill scale, or blending surfaces, the Walter 15X726 delivers consistent, professional results across a wide range of ferrous and non-ferrous metals.
