Built from high-speed steel with a gold oxide coating, it resists wear and provides lubricity during cutting. The taper chamfer eases thread entry by distributing cutting load across the first several threads. With 4 flutes and a right-hand thread direction, this tap suits standard through-hole and blind-hole threading operations in general machining and maintenance environments. It carries an H3 thread limit designation, making it appropriate for use with standard tolerance fits.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in production and maintenance machining applications where 3\/4-10 UNC threaded holes are required. Common applications include threading structural steel, iron castings, aluminum, and similar workpiece materials. The taper chamfer configuration is best suited for through-hole threading where chips can exit freely. Machinists, maintenance technicians, and toolroom operators working in metalworking or industrial maintenance settings are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC thread size for standard unified coarse thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and heat resistance during cutting\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and improves lubricity at the cutting edges\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes entry load across multiple threads, reducing tap breakage risk\u003c\/li\u003e\n  \u003cli\u003e4-flute design delivers balanced cutting forces and good chip clearance\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit designation ensures compatibility with standard tolerance fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom tap for use in any tapping head, drill press, CNC machine, or hand tapping application requiring a 3\/4-10 UNC right-hand straight flute taper tap with a standard shank profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping should be performed by a qualified machinist or maintenance technician using appropriate cutting fluid to extend tool life and improve thread quality. Secure the workpiece firmly before tapping to prevent movement. For taper taps, ensure the hole passes fully through the material when possible to allow chip exit. Always back the tap out periodically to break and clear chips when working in tougher materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\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: 10\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 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\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-20729\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51709304668466,"sku":"BDNA-20729","price":37.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af7f112703e33ab33ffad3039ec6be02.jpg?v=1788454276","url":"https:\/\/voomisupply.com\/products\/import-bdna-20729-straight-flute-tap-3-4-10-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
