Unlike cutting taps, thread forming taps displace material rather than remove chips, producing stronger threads with a better surface finish. This tap is manufactured from high-speed steel with a bright uncoated finish and features a bottoming chamfer with 2.5 chamfered threads, allowing threading close to the bottom of a blind hole. It carries a Class 3B fit with an H5 thread limit, making it suitable for precision threaded assemblies. Machinists and tool-and-die professionals use this tap in CNC and manual tapping operations on ductile materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in materials such as aluminum, mild steel, brass, and other ductile metals where chip-free thread forming is preferred. The bottoming chamfer design is particularly useful in production environments where full thread depth close to the hole bottom is required. Its right-hand thread direction and standard 1\/2-20 UNF specification make it a common selection for automotive, hydraulic, and general mechanical assembly work. The BXB series designation indicates compatibility with standard tap holders sized for its shank diameter of 0.367 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material for stronger, chip-free threads in blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 2.5 chamfered threads for threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across ductile material applications\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H5 thread limit for precision threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eSingle oil groove supports lubrication during the forming process\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 1\/2-20 UNF specification for standard fastener compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders accommodating a 0.367-inch shank diameter.

Apply cutting or tapping oil rated for thread forming to extend tool life and improve thread quality. Secure the workpiece and use a calibrated torque-controlled tapping attachment or CNC rigid tapping cycle where possible to avoid tool breakage. Inspect the tap and holder for runout before production runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BXB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14165-000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52055722918194,"sku":"14165-000","price":78.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77bd7a161793b3795c7b3ab92322fe83.jpg?v=1790037803","url":"https:\/\/voomisupply.com\/products\/balax-14165-000-thread-forming-tap-1-2-20-unf-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
