JONAS C 2 Pcs 4.7" x 4" 120 Grit Surface Conditioning Drum — Open-Box, 51% Off

【Product Advantages】This 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 Tools】This 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. 【Performance】Cutting 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 Purpose】The 120-grit drum is a medium finishing grade and does not possess heavy cutting power; it cannot level large welds or remove heavy burrs. It is primarily used as an intermediate step after rough grinding (40/60-grit) to erase light handling scratches, remove blue-purple heat tint (welding discoloration) on stainless steel, and is commonly used for blending stainless steel weld areas into the surrounding finish. This grit is one of the most commonly specified grits for fine scuffing on metal before applying standard daily paint or topcoats, ensuring perfect paint adhesion without letting scratch patterns show through the finish. 【Woodworking Purpose】The 120-grit drum is designed for wood surface refinement and fine grain highlighting, and is absolutely not for heavy rustic distressing. It serves two core purposes: first, to clean up after aggressive 40/60-grit distressing by reaching deep into the grooves to remove loose wood fuzz and splinters, making the texture safe to touch; second, to be used directly on new wood to create a subtle, high-end wire-brushed wood grain texture, perfectly preparing the wood for subsequent staining, varnishing, or sealing operations.
