Built from high-speed steel with a gold oxide coating, it cuts 1\/2-13 UNC right-hand threads with a plug chamfer that balances starting ease with threading depth. The H3 thread limit provides the tight tolerance class needed for standard fit fastener applications. Overall length is 3-3\/8 inches. This tap is used by machinists, maintenance technicians, pipefitters, and general tradespeople working in metal fabrication, repair, or on-site mechanical work.\u003c\/p\u003e\n\u003cp\u003eThe BDNA-20710 is suited for threading ferrous metals, cast iron, and softer alloys in both shop and field settings. The plug chamfer, with its moderate lead-in, is the most common tap type for general-purpose through-hole and moderately deep blind-hole threading. The 4-flute straight design provides chip clearance in materials that produce short, broken chips. This tap is sold individually and is appropriate for hand tapping or use in low-speed machine tapping setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for standard unified coarse pitch internal threads\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides moderate starting lead — suitable for through-holes and deeper blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers good wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and provides light corrosion protection during storage and use\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent tolerance fit for standard fastener assembly\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design promotes chip control in short-chipping metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock tap for 1\/2-13 UNC internal thread cutting applications.

Secure the workpiece fully before beginning; never tap freehand in critical structural or pressure-bearing applications. For machine tapping, use a low-speed, reversible drill press or tapping head to avoid tap breakage. Follow applicable shop safety standards and wear eye protection when hand tapping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 3-3\/8 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-20710\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51701150581042,"sku":"BDNA-20710","price":23.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e5d5db1701f704026d5adf14c7f81ac.jpg?v=1788398867","url":"https:\/\/voomisupply.com\/products\/import-bdna-20710-straight-flute-tap-1-2-13-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
