Walter Coolcut XX 3-Inch Ceramic Quick-Change Sanding Disc Grit 50

Aggressive Weld Removal in the Palm of Your Hand

For professional welders, time is money, and the Walter Coolcut XX 3" Twist Sanding Disc is built to save you both. When you are faced with a heavy weld seam in a tight corner or need to prep a surface rapidly for the next pass, this 50-grit powerhouse delivers the bite you need. The disc utilizes advanced ceramic grain technology that cuts faster and lasts significantly longer than standard aluminum oxide or zirconia discs. Instead of glazing over and generating excess heat, the Coolcut XX grains micro-fracture to stay sharp, letting you grind down steel, stainless steel, and aluminum with less pressure and less fatigue.

One of the biggest challenges in metal finishing is heat management. Overheating your workpiece can cause blue discoloration on stainless steel or warping on thin aluminum sheet metal. Walter has addressed this with their "Coolcut" formulation, which includes active grinding agents that lubricate the contact zone, keeping the workpiece cooler. This means you can grind aggressively without ruining the metallurgical properties or the aesthetic finish of your base material.

The "Twist" fastening system is a game-changer for workflow. With a simple quarter-turn, you can lock the disc securely onto your die grinder's backing pad. When the disc is spent, or if you need to switch to a finer grit for blending, it twists off just as easily. This compatibility with standard Type R backing pads makes it a universal tool for your existing pneumatic or electric die grinders. Whether you are deburring a machined part, blending a fillet weld, or removing heavy rust, the Walter Coolcut XX 3" Disc gives you the control and power to get the job done right the first time. Sold in a convenient pack of 10, these discs are an essential addition to any welder's consumable arsenal.
