The 1\/8 inch shank diameter mounts directly to standard power drill chucks or flexible shaft tools, making it a practical choice for HVAC technicians, plumbers, and maintenance professionals who need consistent mechanical cleaning action inside tubing, conduit, or heat exchanger passages. Stainless steel bristles resist corrosion and hold up against scale, oxidation deposits, and light debris without shedding or deforming under rotational load.\u003c\/p\u003e\u003cp\u003eThis brush is suited for residential and light commercial maintenance tasks where internal bore cleaning is required. Typical applications include clearing scale buildup from copper or steel tubing, deburring the interior of cut pipe ends, and surface-prepping tube walls before soldering or brazing. The flat brush profile conforms to the bore wall and delivers uniform contact across the cleaning surface. Technicians working on boiler tubes, condenser tubes, and similar heat transfer components will find this brush a reliable rotary cleaning tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat brush profile for uniform contact along tube bore walls\u003c\/li\u003e\n\u003cli\u003eStainless steel fill for corrosion resistance and durability under rotational load\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter fits standard drill chucks and flexible shaft drivers\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.04 pounds for easy single-hand operation\u003c\/li\u003e\n\u003cli\u003eDesigned for power-driven use with consistent mechanical cleaning action\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a rotary power tube brush suitable for use with standard 1\/8 inch shank-compatible drill chucks and flexible shaft tools used in tube and bore cleaning applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by HVAC technicians, plumbers, or maintenance professionals using a power drill or flexible shaft tool. Confirm the chuck or collet is rated for the 1\/8 inch shank before use and tighten securely to prevent slippage during rotation. Ensure the system being cleaned is fully depressurized, drained, and de-energized before inserting the brush into any tubing or bore. Do not exceed the rotational speed rating of the drive tool, and wear appropriate eye protection when operating rotary brush tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Stainless 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: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 0003520500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSBORN","offers":[{"title":"Default Title","offer_id":51746593014066,"sku":"0003520500","price":122.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5099c17e590d8dbee232c75641eb611.jpg?v=1788871581","url":"https:\/\/voomisupply.com\/products\/osborn-0003520500-power-tube-brush-flat-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
