The knotted wire construction delivers high-impact abrading action, making it effective for removing weld spatter, mill scale, rust, and heavy coatings. Wire diameter measures 0.014 inches, providing a balance of flexibility and cutting aggression. Rated to 14,000 RPM, this brush is sized at 2-3\/4 inches in diameter and mounts via a 5\/8-11 threaded arbor. It is used by fabricators, pipe fitters, welders, and maintenance technicians on angle grinders and bench grinders.\u003c\/p\u003e\u003cp\u003eThis cup brush is suited for surface preparation work in fabrication shops, field pipe work, structural steel finishing, and general maintenance environments. The stainless steel fill material is the correct choice when working on stainless steel base materials or in applications where carbon contamination from standard steel wire must be avoided. Single-row construction focuses contact force and makes the brush well suited for weld seam cleaning and edge work on metal components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKnotted wire construction for aggressive cutting action on heavy scale, rust, and weld spatter\u003c\/li\u003e\n\u003cli\u003eStainless steel fill wire prevents carbon cross-contamination on stainless steel workpieces\u003c\/li\u003e\n\u003cli\u003e0.014 inch wire diameter balances flexibility with abrading performance\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor hole for direct mounting to standard angle grinders\u003c\/li\u003e\n\u003cli\u003eSingle-row design concentrates contact force for targeted seam and edge work\u003c\/li\u003e\n\u003cli\u003eRated to 14,000 RPM for compatibility with common angle grinder speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders and bench grinders fitted with a 5\/8-11 threaded spindle.
