The CUMI Cup Wheel for Metal is engineered for portable grinder-based operations, ideal for grinding weld seams, leveling metal surfaces, smoothing structural steel edges, and refurbishing fabricated parts. Available in straight and tapered formats across a grit range of 16 to 220, it supports every stage of work — from bulk weld removal to fine surface preparation before coating, painting, or fabrication assembly.
