Value Collection 2110058350 Knotted Cup Brush 4 in Brass

Product Description

The VALUE COLLECTION 2110058350 is a knotted cup brush designed for aggressive surface preparation and cleaning on metal and other hard materials. Measuring 4 inches in diameter with a 0.02-inch brass wire fill, this single-row brush delivers firm, consistent contact across weld seams, rust scale, paint, and oxidation. The knotted wire configuration concentrates bristle force at the tips, making it well suited for heavy-duty deburring, surface conditioning, and weld cleanup. It is installed on angle grinders and bench grinders by metalworkers, fabricators, maintenance technicians, and general tradespeople who require a reliable abrasive finishing tool.

This cup brush is used in fabrication shops, maintenance facilities, and field service environments where surface prep on steel, pipe, structural members, or castings is required. The brass wire fill is appropriate for applications where ferrous wire contamination must be avoided, such as work on stainless steel, non-ferrous metals, or surfaces where sparks are a concern. The threaded 5/8-11 arbor hole fits standard angle grinder spindle threads commonly found in industrial and light-duty shop equipment.

Installation Notes

This brush is installed by metalworkers and maintenance technicians using standard 5/8-11 threaded arbor angle grinders. Always power down and disconnect or unplug the grinder before mounting or removing the brush. Confirm the tool's rated RPM meets or exceeds the brush's 8,500 RPM maximum rating before operation, and always operate within that limit. Appropriate PPE including face shield, gloves, and hearing protection should be worn during use in accordance with applicable shop safety standards.
