Walter COOLCUT 4-1/4" x 4" Flap Drum, 80 Grit

Master Your Aluminum Finishes with COOLCUT™

For welders and fabricators looking to achieve a flawless linear finish on aluminum projects, the Walter 07J448 COOLCUT™ Flap Drum is an essential addition to your abrasive arsenal. This 80 grit drum is perfectly sized at 4-1/4" diameter by 4" width, making it compatible with standard linear finishing tools (burnishers). It serves as the ideal starting point for removing light weld discoloration, scratches, or handling marks before moving to finer grits for a satin or mirror finish.

Working with aluminum requires abrasives that can handle the material's softness without gumming up. Standard drums often fail quickly as the aluminum heats up and adheres to the grit. The COOLCUT™ technology is specifically formulated to prevent loading and glazing. This means the abrasive grains remain exposed and sharp, cutting cleanly rather than rubbing and generating excess heat. The result is a cooler grinding zone and a cleaner finish, saving you time and frustration on the job.

The flexibility of the flap configuration allows the drum to conform slightly to the surface, ensuring smooth blending without gouging. Whether you are restoring an aluminum truck bed, finishing a railing, or prepping a custom fabrication piece, this drum provides the control and quality you expect from Walter products. The 80 grit texture offers aggressive enough removal for surface imperfections while leaving a consistent grain that is easy to refine in subsequent steps.

Why Welders Choose This Drum:

• No Clogging: Keep working without stopping to clean or change the drum.
• Cool Running: Minimize heat input into the base metal.
• Versatile Utility: Excellent for both graining and light stock removal on non-ferrous metals.
