JONAS C 2 Pcs 40 Grit Stripping Drum, Abrasive Drawing Wheel Burnishing Wheel, 4.5" x 4" Surface Conditioning Tool Drum for Removing Metal Rust, Paint, Scale and Coatings

Product AdvantagesThis surface conditioning drum is durable, cost-effective, and delivers consistent, reliable performance throughout its service life. Its open-web construction resists loading and clogging, helping maximize productivity while reducing downtime. The open structure also allows the drum to run cooler during operation, reducing the risk of heat discoloration, burn marks, and other heat-related damage on both metal and wood surfaces. | Suitable ToolsThis 4" x 4" surface conditioning drum is designed for use with burnishing and surface conditioning machines. Compared with conventional grinding wheels and abrasive discs, it is better suited for processing large workpieces, offering easier operation, reduced operator fatigue, a wider contact area, and improved productivity. In addition, the cross-lock core design provides enhanced stability, smoother operation, and increased user safety. | PerformanceCutting Aggressiveness: 40 grit > 60 grit > 120 grit > 240 grit > 320 grit ( For the same grit size, drums with sandpaper deliver faster material removal and more aggressive cutting performance than those without ). Surface Roughness: 40 grit > 60 grit > 120 grit > 240 grit > 320 grit. Brushed Finish Fineness: 320 grit > 240 grit > 120 grit > 60 grit > 40 grit. Relative Surface Reflectivity: 320 grit > 240 grit > 120 grit > 60 grit > 40 grit. | Metalworking PurposeThe 40-grit drum is a heavy-duty cleaning grade primarily optimized for removing the most stubborn surface contaminants, such as heavy rust, thick mill scale, old industrial coatings, and light-to-moderate weld spatter and residue. It quickly exposes the base metal and reveals underlying pitting or surface defects. Due to its aggressive cutting action, it leaves a distinct scratch pattern, making it ideal only for providing a high-adhesion rough profile required for thick industrial anti-corrosion paints or heavy primers. It is absolutely not suitable for standard thin daily paint or pre-polishing prep. | Woodworking PurposeThe 40-grit drum is engineered for heavy-duty wood distressing on hardwoods (like oak or ash) or aged wood/reclaimed timber, aggressively clearing away soft fibers to leave deep, rustic relief textures and prominent growth rings. When used on softwoods (like pine or cedar), it creates a highly pronounced weathered grain effect perfect for highly aggressive log-cabin aesthetics, rustic bar counters, or heavy outdoor timber (Note: Not recommended for standard softwood furniture as it cuts exceptionally deep and can alter the structural geometry).
