07J428 - Walter Coolcut 80 Grit Flap Drum for Line-Mate Finisher

Premium Linear Finishing with Walter Coolcut Flap Drums

The Walter Surface Technologies 07J428 Coolcut Flap Drum is a high-performance abrasive tool designed to elevate your metal finishing processes. Engineered specifically for the LINE-MATE linear finishing system, this 4-1/2" x 2" drum features premium aluminum oxide cloth flaps that deliver consistent, uniform results across a variety of metals. Whether you are working with stainless steel, steel, or aluminum, the Coolcut series is renowned for its ability to refine surfaces gently while effectively removing imperfections.

Industrial fabricators rely on the 80 grit composition of this drum for intermediate finishing stages. It strikes the perfect balance between material removal and surface conditioning, making it an excellent choice for blending weld seams, removing light scratches, and preparing surfaces for final polishing. The flap configuration allows the abrasive to contour slightly to the workpiece, ensuring that even curved or irregular surfaces receive a uniform finish without gouging or undercutting.

Durability is a hallmark of Walter abrasives. The 07J428 is constructed to resist clogging and loading, which is particularly beneficial when working with softer metals like aluminum that tend to gum up inferior abrasives. This longevity translates to reduced downtime for tool changes and lower overall consumable costs for your shop. By maintaining a cool cutting action, this flap drum also minimizes heat buildup, protecting your workpiece from heat discoloration and warping.

Key Applications:

• Line Finishing: Creating consistent grain lines on architectural stainless steel.
• Blending: Merging coated abrasive finishes with the surrounding base metal.
• Deburring: Removing sharp edges and burrs after cutting or machining.
• Surface Conditioning: Preparing metal surfaces for painting, coating, or further polishing.
