It features a 5\/8-inch brush diameter with 0.005-inch steel wire and a 1\/4-inch trim length, delivering consistent, controlled abrasion on metal surfaces. The 1\/8-inch shank mounts directly into a rotary tool, die grinder, or drill, making it a practical choice for HVAC techs, pipefitters, electricians, and fabricators who need a small-footprint brush for weld cleanup, rust removal, or port cleaning without disturbing surrounding material.\u003c\/p\u003e\u003cp\u003eThis cup brush is suited for light-duty rotary tool applications in both shop and field environments. Its compact 5\/8-inch diameter makes it effective for internal bore cleaning, connector prep, and small weld seam work where a full-size cup brush cannot reach. The crimped-wire construction provides a degree of flexibility during contact, reducing the risk of gouging on softer base metals. It is sold individually and is a common consumable on service trucks and in fabrication shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch brush diameter for access in confined or recessed areas\u003c\/li\u003e\n\u003cli\u003e0.005-inch crimped steel wire for controlled, flexible abrasion\u003c\/li\u003e\n\u003cli\u003e1\/4-inch trim length provides consistent wire exposure and wear life\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank fits standard rotary tools and die grinders\u003c\/li\u003e\n\u003cli\u003eRated to 37,000 RPM for compatibility with high-speed rotary tools\u003c\/li\u003e\n\u003cli\u003eOverall length of 2 inches for reach into ports and bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with rotary tools and die grinders equipped with a 1\/8-inch collet or chuck.

Always confirm the tool's no-load RPM rating is at or below the brush's 37,000 RPM maximum. Wear appropriate eye protection and a face shield when operating wire brushes at high speed. Inspect the wire fill for splayed or broken wires before each use and discard the brush if damage is found.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Type\u003c\/strong\u003e: Crimped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Type\u003c\/strong\u003e: Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 37,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191521\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: 98434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51539825164594,"sku":"98434","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92a49348a7d32147f8f191edb881b737.jpg?v=1785844458","url":"https:\/\/voomisupply.com\/products\/weiler-98434-cup-brush-5-8-in-steel-crimped-37000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
