It is designed for surface preparation, light deburring, blending, and cleaning on materials where a fine, controlled abrasive action is needed without aggressive metal removal. The brush mounts via a 5\/8-11 threaded arbor hole with an internal nut and is rated for a maximum of 6,600 RPM. A trim length of 1.25 inches provides the filament exposure needed for consistent contact on contoured or flat workpiece surfaces. This tool is typically installed and operated by machinists, maintenance technicians, and fabricators working with angle grinders or bench grinders.\u003c\/p\u003e\u003cp\u003eThis cup brush is suited for fine finishing work on metal, composite, and similar hard surfaces in light industrial and maintenance environments. Its nylon fill with silicon carbide abrasive makes it appropriate for applications where steel wire brushes would cause excessive surface damage or contamination. Common use cases include weld seam blending, surface conditioning before coating, and light scale removal on aluminum, stainless steel, and other materials sensitive to ferrous contamination. It is sold individually and is a direct fit for grinders accepting a 5\/8-11 threaded arbor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch brush diameter provides broad surface coverage in a single pass\u003c\/li\u003e\n\u003cli\u003e120-grit silicon carbide fill delivers fine, controlled abrasive action\u003c\/li\u003e\n\u003cli\u003eCrimped nylon filaments conform to irregular or contoured surfaces\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor with internal nut for secure grinder mounting\u003c\/li\u003e\n\u003cli\u003e1.25-inch trim length maintains consistent filament-to-surface contact\u003c\/li\u003e\n\u003cli\u003e6,600 RPM maximum rating suits standard angle grinder operating speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders and bench grinders equipped with a 5\/8-11 threaded arbor.
