It produces a 4-48 UNF thread profile using three straight flutes and a plug chamfer, making it well suited for through-hole threading applications where chips can exit freely. The body is ground from high-speed steel and carries a gold oxide coating that provides light lubricity and improved wear resistance. At 1-7\/8 inches overall length, it fits standard tap handles and machine setups used in precision machining and light fabrication work. Machinists, toolmakers, and maintenance technicians are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is appropriate for threading small-diameter holes in machine components, brackets, enclosures, and fixtures where a 4-48 UNF fine-thread fastener is required. The plug chamfer — typically 3 to 5 threads of lead — allows the tap to start easily in a drilled through-hole and is the most common style for general production and repair work. It is used in both manual and CNC tapping operations at low spindle speeds with appropriate cutting fluid.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-48 UNF thread form for fine-pitch small-diameter threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for easy entry in through-hole applications\u003c\/li\u003e\n\u003cli\u003e3 straight flutes for chip clearance in open through-holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eGold oxide coating adds wear resistance and light lubricity\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent fit within standard tolerance range\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction — standard for most fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock tap for applications requiring a 4-48 UNF plug-style straight flute tap in high-speed steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by hand or machine into a pre-drilled hole sized to the correct tap drill diameter for 4-48 UNF threads. Always use a quality cutting fluid or tapping compound to extend tool life and improve thread finish. Secure the workpiece firmly before tapping and back off the tap periodically to break chips and prevent binding. Replace worn or broken taps before reuse — a snapped tap in a blind hole is difficult to remove.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/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\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-20751\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51691595465010,"sku":"BDNA-20751","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/851c19d5a37f2c06044cf7bbed69f651.jpg?v=1788287517","url":"https:\/\/voomisupply.com\/products\/import-bdna-20751-straight-flute-tap-4-48-unf-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
