Built with stainless steel fill wire in the 0.010 to 0.019 inch diameter range, it delivers the cutting action needed to remove rust, scale, weld spatter, and oxidation without contaminating carbon steel or stainless steel base materials. The 4-inch outside diameter and 3\/8-inch face width keep the working area focused. Rated to 12,500 RPM, it is sized and balanced for use on right angle grinders. The threaded 5\/8-11 arbor hole mounts directly to standard right angle grinder spindles without an adapter shank.\u003c\/p\u003e\u003cp\u003eThis brush is used in fabrication shops, pipe yards, structural steel work, and maintenance environments where surface prep must meet weld inspection or coating standards. It suits both light industrial and heavy-duty field applications. The stainless steel wire construction makes it the correct choice when cross-contamination from carbon steel wire must be avoided, such as on stainless steel pipe welds, food-grade equipment repairs, or marine structural work. Licensed fabricators and ironworkers are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKnotted wire configuration provides aggressive cutting action for weld cleaning and rust removal\u003c\/li\u003e\n\u003cli\u003eStainless steel fill wire prevents cross-contamination on stainless or corrosion-sensitive base materials\u003c\/li\u003e\n\u003cli\u003e12,500 RPM maximum speed rating sized for standard right angle grinders\u003c\/li\u003e\n\u003cli\u003eThreaded 5\/8-11 arbor hole mounts directly to common grinder spindles\u003c\/li\u003e\n\u003cli\u003e3\/4-inch trim length maintains consistent wire contact throughout tool life\u003c\/li\u003e\n\u003cli\u003e3\/8-inch face width concentrates wire action for seam and bead cleaning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on right angle grinders with a 5\/8-11 threaded spindle.

Verify the grinder's rated RPM meets or does not exceed the 12,500 RPM maximum before mounting. Power down and disconnect the grinder from its power source before threading on or removing the brush. Always install the proper guard for the grinder and confirm the brush spins freely before resuming work. Wear appropriate eye and face protection during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Style\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Knotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilament Wire Diameter Range\u003c\/strong\u003e: 0.010 to 0.019 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Right Angle Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WEILER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51539404259634,"sku":"13416","price":74.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9d04f2a21305df86618aef8ddd7af29.jpg?v=1785839364","url":"https:\/\/voomisupply.com\/products\/weiler-13416-knotted-wheel-brush-4-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
