B46B Scratch Brush Brass 4 Row 16 Column","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe BRUSH RESEARCH MFG. B46B is a crimped-wire scratch brush with brass fill and a wood shoe-style handle, designed for surface preparation, cleaning, and deburring in trade and light industrial applications. The brush features 4 rows and 16 columns of brass bristles arranged across an overall length of 10.25 inches. Brass fill is non-sparking and resistant to corrosion, making it appropriate for use on softer metals and in environments where ferrous contamination must be avoided. The shoe handle provides a low-profile grip suited to detail work and confined-surface cleaning. HVAC, plumbing, and general mechanical technicians commonly keep this type of brush on hand for flux application prep, fitting cleaning, and light scale removal.\u003c\/p\u003e\n\u003cp\u003eThe B46B is suited for both residential and light commercial service work. Common applications include cleaning copper pipe fittings before soldering, removing oxidation from electrical contacts, deburring machined surfaces, and general surface preparation on metals and wood. The crimped brass bristles provide moderate abrasive action without scoring soft base materials. The shoe handle style allows the brush to be worked flat against a surface or guided into tight channels where a standard block-style brush would not fit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCrimped brass bristles provide consistent abrasive action on soft metals and oxidized surfaces\u003c\/li\u003e\n  \u003cli\u003e4-row by 16-column fill pattern delivers broad, even coverage per stroke\u003c\/li\u003e\n  \u003cli\u003eOverall length of 10.25 inches with a low-profile wood shoe handle for controlled grip\u003c\/li\u003e\n  \u003cli\u003eBrass fill is non-sparking and will not introduce ferrous contamination to the work surface\u003c\/li\u003e\n  \u003cli\u003eNo scraper included  -  dedicated brush-only tool for surface prep and cleaning tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose scratch brush for surface preparation, fitting cleaning, and deburring tasks across HVAC, plumbing, electrical, and mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool requires no installation. Use appropriate personal protective equipment, including eye protection, when operating wire brushes, as bristle fragments can become projectiles under load. Inspect bristles before each use and replace the brush if fill is damaged or significantly worn. For use on energized electrical components, ensure the circuit is de-energized and locked out before brushing contacts or terminals per NFPA 70E guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Type\u003c\/strong\u003e: Scratch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Type\u003c\/strong\u003e: Crimped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Brass\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: Shoe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Rows\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Columns\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Scraper\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 11.5 x 8 x 4 inches\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: B46B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRUSH RESEARCH MFG","offers":[{"title":"Default Title","offer_id":67913769419058,"sku":"B46B","price":23.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d21dd5b5b23156d7348b23858cf7f021.jpg?v=1791246543","url":"https:\/\/voomisupply.com\/products\/brush-research-mfg-b46b-scratch-brush-brass-4-row-16-column","provider":"Voomi Supply","version":"1.0","type":"link"}
