Built from high-speed steel (HSS) with a gold oxide coating, this tap delivers reliable performance in ferrous and non-ferrous materials. The taper chamfer lead eases thread entry and reduces the force required to start the cut. With 4 flutes and a right-hand thread direction, the BDNA-20780 is suited for through-hole and general-purpose tapping operations performed by machinists, tool-and-die makers, and maintenance technicians in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in applications requiring a 7\/8-14 UNF thread form, a fine-pitch unified thread standard common in precision fastener assemblies, hydraulic fittings, and mechanical components. It is appropriate for both manual tapping with a tap wrench and machine tapping on drill presses or CNC equipment where straight flute geometry is preferred. The taper chamfer style makes it well suited for starting threads in open or through holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size: 7\/8-14 UNF right-hand thread\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for stable chip control in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer lead for easier thread starting and reduced entry force\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for controlled pitch diameter tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool for general-purpose tapping of 7\/8-14 UNF threaded holes in metalworking, maintenance, and machining operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed and operated by qualified machinists or maintenance technicians familiar with thread-cutting procedures. Always ensure the workpiece is securely clamped and that the tap is properly aligned with the hole axis before beginning the cut. Use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Follow shop safety protocols and equipment manufacturer guidelines when using in a machine tapping setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\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-20780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51700747665714,"sku":"BDNA-20780","price":49.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_ad0d1202-2bc6-4cce-aa6a-0bef4b9b4fed.jpg?v=1788394722","url":"https:\/\/voomisupply.com\/products\/import-bdna-20780-straight-flute-tap-7-8-14-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
