B61 Brass Scratch Brush 9 Rows 10 Columns","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe BRUSH RESEARCH MFG. B61 is a brass-fill scratch brush built for surface preparation, cleaning, and light material removal on metal, pipe, and fittings. It features a straight-back wood handle and a stiff brass bristle configuration arranged in 9 rows and 10 columns, giving it consistent contact across the work surface. At 8.875 inches overall length with a trim length of 0.625 inches, the B61 is sized for controlled hand work. Brass bristles are non-sparking and resist corrosion, making this brush well-suited for use on copper, brass, and soft metal components without leaving ferrous contamination. Plumbers, HVAC technicians, and pipefitters commonly use this type of brush for flux application prep, fitting cleanup, and oxidation removal before soldering or brazing.\u003c\/p\u003e\n\u003cp\u003eThe B61 is used across residential and light commercial trade applications where hand brushing is required prior to joining, coating, or inspection. Typical scenarios include cleaning copper pipe ends and fittings before soldering, removing light oxidation from brass valves, and surface prep on aluminum or soft alloy components. The 2.625-inch brush width provides good coverage on standard pipe fittings and flat surfaces. The straight-back handle style allows direct downward pressure and is comfortable for extended use in tight mechanical spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass bristle fill  -  non-sparking and non-ferrous, safe for use on copper, brass, and aluminum\u003c\/li\u003e\n  \u003cli\u003e9-row by 10-column bristle pattern for even surface contact\u003c\/li\u003e\n  \u003cli\u003eStiff bristle grade for effective oxidation and flux residue removal\u003c\/li\u003e\n  \u003cli\u003eStraight-back wood handle, 8.875 inches overall length\u003c\/li\u003e\n  \u003cli\u003e2.625-inch brush width covers standard pipe fittings and valve bodies efficiently\u003c\/li\u003e\n  \u003cli\u003e0.625-inch trim length maintains stiffness under moderate hand pressure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose hand scratch brush suitable for plumbing, HVAC, and pipefitting surface preparation tasks involving copper, brass, and soft metal components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is a hand tool used by plumbers, HVAC technicians, and pipefitters during surface preparation before soldering, brazing, or mechanical joining. No power source is required. Always brush in a well-ventilated area when working with flux or removing oxidation from heated metals. Inspect bristles periodically for wear or splaying, as a deformed brush face reduces cleaning effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Type\u003c\/strong\u003e: Stiff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Rows\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Columns\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Width\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrim Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Straight Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.375 pounds\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: BRUSH RESEARCH MFG.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B61\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRUSH RESEARCH MFG","offers":[{"title":"Default Title","offer_id":67907530916146,"sku":"B61","price":24.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d590013d871f84bf476f4aadd9f5e28b.jpg?v=1791180153","url":"https:\/\/voomisupply.com\/products\/brush-research-mfg-b61-brass-scratch-brush-9-rows-10-columns","provider":"Voomi Supply","version":"1.0","type":"link"}
