Built from high-speed steel (HSS) with a gold oxide coating, it cuts 9\/16-12 UNC right-hand threads with four flutes and an H3 thread limit for consistent fit and dimensional accuracy. The overall length measures 3-19\/32 inches. This tap is suited for use in machine shop, maintenance, and field repair applications where standard UNC threads are required. Machinists, maintenance technicians, and trade professionals use this tap in drill presses, lathes, CNC machines, or with a tap wrench for hand tapping.\u003c\/p\u003e\n\u003cp\u003eThe BDNA-20711 is applicable to general metalworking tasks requiring 9\/16-12 UNC internal threads. The plug chamfer — typically 3 to 5 threads of lead — makes it effective for starting threads in through-holes as well as moderately deep blind holes. It is commonly used in HVAC equipment assembly, structural fabrication, machinery repair, and similar industrial trades where 9\/16-inch coarse-thread fasteners are standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-12 UNC thread form for coarse-thread fastener applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across steel, iron, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and improves lubricity during cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides easy thread starting in through-holes and shallow blind holes\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures dimensional tolerance consistency\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides chip clearance and stable cutting action\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or working tap for any application requiring 9\/16-12 UNC right-hand internal threads.

Always use an appropriate cutting fluid or tapping compound for the material being threaded to extend tap life and improve thread quality. Secure the workpiece firmly and align the tap perpendicular to the hole before beginning to cut. Advance the tap in short increments and reverse periodically to break chips and prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-19\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51701097595186,"sku":"BDNA-20711","price":25.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa227f22de945df67f2907ea99f93f57.jpg?v=1788398174","url":"https:\/\/voomisupply.com\/products\/import-bdna-20711-straight-flute-tap-9-16-12-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
