Built with stainless steel wire fill, it delivers effective cleaning action without carbon contamination on stainless steel base materials or other corrosion-sensitive surfaces. The brush measures 1-1\/8 inches in diameter and mounts via a 6 mm shank, making it compatible with die grinders and other rotary tools. Rated to a maximum of 22,000 RPM, it suits high-speed finishing work. Licensed trades and fabrication shops rely on this type of end brush for weld prep, scale removal, and surface cleaning in tight or recessed areas inaccessible to larger wheel brushes.\u003c\/p\u003e\n\u003cp\u003eThis end brush is suited for use in light fabrication, maintenance, and repair applications where stainless steel wire is required to prevent cross-contamination. The knotted-wire construction provides more aggressive cutting action compared to crimped-wire configurations. Common applications include tube interiors, pipe ends, bore surfaces, and weld joint cleaning on stainless steel or other alloy components. It is a single-pack unit, making it straightforward to stock as a consumable or add individually to a job kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel knotted wire fill — aggressive cleaning without carbon contamination\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch brush diameter for targeted surface access\u003c\/li\u003e\n  \u003cli\u003e6 mm shank fits standard die grinder and rotary tool chucks\u003c\/li\u003e\n  \u003cli\u003e22,000 maximum RPM rating for high-speed operation\u003c\/li\u003e\n  \u003cli\u003eHollow center construction\u003c\/li\u003e\n  \u003cli\u003eShank included — ready to mount out of the package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard end brush replacement for use with die grinders and rotary tools accepting a 6 mm shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and use should be performed by personnel familiar with rotary abrasive and power brush safety practices.
