A 9-inch fiber resin abrasive disc with 100-grit aluminum oxide for metal surface finishing, weld and edge blending, and general surface preparation. It is intended for use with fiber-disc backing pads and a 5/8"-11 arbor. The abrasive grain fractures during use to expose fresh cutting surfaces; the resin formulation and fiber backing are designed for durability and tear resistance.

Grind-Pattern Wall Art Panels
Create large steel or aluminum wall panels with directional grind patterns. Use the 9 in. 100g AO disc to remove mill scale, feather edges, and lay consistent swirls; the fracturing aluminum oxide keeps the cut fresh for even texture. Finish with clear coat or patina for depth.
Industrial Coffee Table Frame
Fabricate a welded steel base and use the disc to blend welds, radius sharp edges, and prep for powder coat or clear lacquer. The tough fiber backing resists tearing on corners, and the 9 in. diameter speeds up leveling long seams.
Garden Scrap Sculpture Finish
Assemble a garden sculpture from reclaimed metal and use the disc to unify the surface, remove rust, and apply a consistent brushed finish. The resin bond extends disc life on mixed materials and curves.
Custom Fire Pit With Seamless Welds
Build a sheet-metal fire pit and use the disc to blend interior and exterior welds, chamfer edges, and prep for high-temp paint. Quick-lock 5/8-11 backing pads make disc changes fast during multi-stage finishing.
