It features a single-cut American pattern tooth configuration and tapers slightly toward the point, which allows controlled material removal in tight radii and curved profiles. At 0.24 pounds, this is a lightweight hand file suited for bench work and field use. Licensed HVAC techs, plumbers, and pipefitters reach for this file when dressing burrs from drilled or punched round holes, smoothing pipe ends, or fitting conduit knockouts.\u003c\/p\u003e\u003cp\u003eThe 21846NN is a general-purpose trade file appropriate for metalworking tasks across HVAC, plumbing, electrical, and light fabrication work. Its round cross-section and tapered profile make it especially useful when enlarging or cleaning up circular openings in sheet metal, conduit boxes, pipe flanges, or similar components. The single-cut pattern produces a smoother finish than double-cut files and is well suited to finishing passes rather than aggressive stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-inch length with slight taper toward the point for controlled filing in circular profiles\u003c\/li\u003e\n\u003cli\u003eRound cross-section targets circular openings and concave surfaces directly\u003c\/li\u003e\n\u003cli\u003eSingle-cut American pattern delivers a smoother finish and finer control\u003c\/li\u003e\n\u003cli\u003eBlack Diamond tooth finish provides consistent cutting performance\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.24 pounds for extended hand use without fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose round bastard file suitable for metalworking applications across HVAC, plumbing, electrical, and fabrication trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHand files require no power source, but always inspect the tang before use and fit an appropriate handle to prevent injury. Wear eye protection when filing metal to guard against swarf. Use smooth, consistent strokes with moderate pressure; lifting on the return stroke extends file life. Keep files dry and stored separately to prevent tooth damage from contact with other tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Type\u003c\/strong\u003e: Single Cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePattern\u003c\/strong\u003e: American Pattern\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfile\u003c\/strong\u003e: Round, tapered toward point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: APEX TOOL GROUP LLC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21846NN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APEX TOOL GROUP","offers":[{"title":"Default Title","offer_id":51523362718002,"sku":"21846NN","price":30.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adb60e75dd5928e173fec0aea03df850.jpg?v=1785440777","url":"https:\/\/voomisupply.com\/products\/apex-tool-group-llc-21846nn-round-bastard-file-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
