Constructed with steel fill, it delivers aggressive scrubbing action suited for removing scale, corrosion, and deposits from metal surfaces. The 1\/8 inch shank diameter allows it to chuck directly into standard rotary tools, drill motors, and flexible shaft machines. HVAC technicians, plumbers, and pipe fitters reach for this brush when prepping tube interiors before brazing, soldering, or inspection. The flat brush profile conforms to tube walls to maximize contact and cleaning efficiency on each pass.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for light industrial and trade applications where tube bore cleaning is part of routine service or installation prep. Typical use cases include cleaning heat exchanger tubes, condenser tubes, copper pipe ends, and similar small-diameter bores. Its steel fill makes it appropriate for ferrous and non-ferrous metal surfaces that require mechanical abrasion rather than softer nylon or brass bristle action. The 1\/8 inch shank keeps it compatible with commonly available rotary tooling found on most service vehicles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat brush profile maximizes contact with tube bore walls during rotation\u003c\/li\u003e\n  \u003cli\u003eSteel fill provides aggressive cleaning action for scale, rust, and deposits\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits standard rotary tools and drill chucks\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.031 pounds — easy to carry in a standard tool pouch\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction with no separate mandrel required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rotary tools, drill motors, and flexible shaft machines accepting a 1\/8 inch round shank.

Always wear appropriate eye protection when operating power brushes, as wire bristles can shed under load. Verify the tool RPM rating does not exceed the brush manufacturer maximum before use. Isolate and de-energize any system being serviced before accessing tube interiors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSBORN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0003508700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSBORN","offers":[{"title":"Default Title","offer_id":51749687492914,"sku":"0003508700","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad9856dff785fe6e2b93c671e9aebcef.jpg?v=1788909211","url":"https:\/\/voomisupply.com\/products\/osborn-0003508700-flat-steel-power-tube-brush","provider":"Voomi Supply","version":"1.0","type":"link"}
