The brush measures 4 inches in diameter with a 0.02-inch wire diameter and a single-row configuration. A threaded M16x2.00 arbor hole mounts the brush directly to angle grinders and compatible threaded spindle tools. Rated to 8,500 RPM maximum, this medium-grade brush delivers the wire tension and bite needed for paint removal, rust stripping, and weld spatter cleanup in fabrication and mechanical service environments. Licensed trades and maintenance professionals rely on this style of brush for pre-weld and pre-coat surface conditioning.\u003c\/p\u003e\u003cp\u003eThis cup brush is suited for use in metal fabrication shops, HVAC mechanical rooms, plumbing and pipe fitting work, and general industrial maintenance. The knotted wire construction handles heavy-duty stripping tasks where crimped brushes fall short. Single-row geometry concentrates wire contact on a tighter working surface, making it effective for cleaning weld seams, pipe ends, and localized corrosion spots. It is sold individually and is a practical consumable for service vans and shop tool stations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter knotted steel wire cup brush for high-impact surface prep\u003c\/li\u003e\n\u003cli\u003e0.02-inch wire diameter with medium grade provides aggressive cutting action\u003c\/li\u003e\n\u003cli\u003eThreaded M16x2.00 arbor mounts to standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003e8,500 RPM maximum rating for use with common portable grinders\u003c\/li\u003e\n\u003cli\u003eSingle-row wire configuration concentrates contact force on the work surface\u003c\/li\u003e\n\u003cli\u003e24 mm trim length maintains consistent wire projection throughout brush life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders and rotary tools equipped with an M16x2.00 threaded spindle.

Confirm the tool RPM rating meets or stays below the 8,500 RPM maximum marked on the brush before operation. Wear appropriate eye, face, and hand protection during use, as wire fragments can break free under load.
