The set includes bottoming, plug, and taper chamfer taps, allowing machinists and trade professionals to start, advance, and finish threads in a single coordinated workflow. Each tap features 4 flutes ground from high-speed steel (HSS) and carries a gold oxide finish that provides light lubricity and corrosion resistance during use. Overall length is 4-11\/16 inches. The H4 thread limit designation indicates a tolerance class suited for general-purpose UNF threading applications where moderate fit and clearance are required.\u003c\/p\u003e\u003cp\u003eThis tap set is suited for threading operations on ferrous and non-ferrous metals in maintenance, repair, and manufacturing environments. The 7\/8-14 UNF thread specification is common in hydraulic fittings, automotive components, and precision mechanical assemblies where fine-pitch threads are required for vibration resistance or tight sealing. The three-chamfer configuration makes the set appropriate for both through-hole and blind-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-piece set includes bottoming, plug, and taper taps for complete threading sequences\u003c\/li\u003e\n\u003cli\u003e7\/8-14 UNF thread specification for fine-pitch internal threading\u003c\/li\u003e\n\u003cli\u003e4-flute design provides efficient chip evacuation and thread formation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of metal workpieces\u003c\/li\u003e\n\u003cli\u003eGold oxide finish reduces friction and provides light corrosion protection\u003c\/li\u003e\n\u003cli\u003eH4 thread limit for general-purpose UNF fit and clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 7\/8-14 UNF threads per standard UNF thread specifications.

Always secure the workpiece firmly before beginning the tapping operation and use an appropriate cutting fluid for the material being threaded. Begin with the taper tap to start the thread, progress to the plug tap, and finish with the bottoming tap when threading to the bottom of a blind hole. Inspect each tap for wear or chipping before use to avoid thread damage or tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Types\u003c\/strong\u003e: Bottoming, Plug, Taper\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\u003eOverall Length\u003c\/strong\u003e: 4-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces in Set\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-20695\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51692180898098,"sku":"BDNA-20695","price":212.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e16cbcac6d48a39ddb179bf962d09fb2.jpg?v=1788294201","url":"https:\/\/voomisupply.com\/products\/import-bdna-20695-tap-set-7-8-14-unf-hss-gold-oxide-3-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
