The brush features a 3\/4-inch diameter with knotted steel wire filaments ranging from 0.0101 to 0.0200 inches in diameter, delivering firm, consistent contact pressure across the work surface. A 6 mm shank diameter provides secure chuck engagement, and the brush is rated to a maximum of 22,000 RPM, making it suitable for use with die grinders and rotary tools commonly found in fabrication, maintenance, and industrial service environments. Weighing 0.15 pounds, it is a lightweight consumable replacement item stocked by the individual unit.\u003c\/p\u003e\u003cp\u003eThis end brush is used in applications where a standard cup or wheel brush cannot reach confined areas, weld joints, pipe ends, or tight inside-corner profiles. It is well suited for metal fabrication shops, pipe fitting, structural steel work, and general MRO maintenance tasks. The knotted wire construction is preferred over crimped wire when the job requires more aggressive cutting action and faster material removal on harder base metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKnotted steel wire construction delivers aggressive cutting action for weld cleaning, scale removal, and surface prep\u003c\/li\u003e\n\u003cli\u003e3\/4-inch brush diameter sized for access in confined areas and tight profiles\u003c\/li\u003e\n\u003cli\u003eWire diameter range of 0.0101 to 0.0200 inches for firm, consistent contact\u003c\/li\u003e\n\u003cli\u003e6 mm shank diameter fits standard die grinder and rotary tool chucks\u003c\/li\u003e\n\u003cli\u003e22,000 RPM maximum rating compatible with high-speed rotary tools\u003c\/li\u003e\n\u003cli\u003eHollow center design and non-piloted, non-bridled construction for straightforward fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard knotted wire end brush replacement for use with die grinders and rotary tools that accept a 6 mm shank, operating at up to 22,000 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by trade professionals or qualified maintenance technicians using a die grinder or compatible rotary tool with a matching chuck size. Always power down and disconnect the tool from its power source before inserting or removing the brush.
