Walter Coolcut XX 4.5-Inch Resin Fiber Sanding Disc 24 Grit (5-Pack)

Aggressive Weld Removal and Stock Reduction

For professional welders and fabricators, time is money, and the Walter 15X452V Coolcut XX sanding disc is built to save both. This 5-pack of 4-1/2 inch discs is engineered for the most demanding material removal tasks. With a coarse 24 grit, these discs are not designed for finishing; they are designed for hogging off metal. If you need to level a heavy butt weld, remove thick mill scale, or bevel a plate edge for penetration, this is the tool for the job. The Coolcut XX utilizes advanced ceramic grain technology that cuts faster and lasts significantly longer than conventional zirconia or aluminum oxide discs. This means fewer disc changes, less downtime, and more arc time.

The "Coolcut" name isn't just branding; it's a functional promise. Grinding stainless steel often presents the challenge of heat buildup, which can warp thin materials or ruin the corrosion resistance of the alloy. These discs feature active cooling agents bonded directly into the abrasive matrix, helping to dissipate heat and prevent the workpiece from overheating. This feature is critical when working on expensive alloys where surface integrity is non-negotiable. The 7/8" arbor hole is the industry standard, ensuring compatibility with almost every 4-1/2" and 5" angle grinder on the market when used with an appropriate backing pad.

Safety and performance go hand in hand with the Coolcut XX. The fiber backing is reinforced to resist tearing and edge chipping, even when grinding on sharp corners or jagged edges. To get the most out of these discs, it is highly recommended to use them with a rigid backing pad with cooling ribs, such as the Walter Turbo Pad. This combination allows for increased airflow behind the disc and provides the stiffness necessary to drive the ceramic grains deep into the metal for maximum stock removal. This 5-pack configuration is perfect for tool cribs, service trucks, or personal welding rigs where storage space is at a premium but performance cannot be compromised.
