Unlike cutting taps, thread forming taps displace material rather than cutting it, resulting in stronger threads with no chips to clear. This tap is built from high-speed steel with a bright uncoated finish and carries a 3B class of fit with an H6 thread limit. It is used by machinists, tool and die workers, and maintenance professionals in production and repair environments where clean, chip-free threading is required in ductile metals.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading in materials that flow well under cold forming conditions, including low-carbon steel, aluminum, brass, and similar ductile alloys. The bottoming chamfer style allows threading close to the bottom of a blind hole, making it well suited to tight-tolerance assemblies where maximum thread engagement depth is needed. The BXB series designation indicates a standard bottoming geometry from BALAX. A single oil groove supports lubrication during the forming process, which is essential for tool life and thread quality in production tapping operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces no chips, eliminating chip-packing risk 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 for durability across a range of ductile workpiece materials\u003c\/li\u003e\n\u003cli\u003eH6 thread limit for consistent 3B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eSingle oil groove aids lubrication and reduces forming torque\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, suitable for standard tapping equipment and tap handles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for 3\/8-16 UNC blind hole threading applications in standard tapping chucks, holders, and reversing tap heads that accept a 0.381-inch shank diameter with a 0.286-inch square drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require proper lubrication at all times  -  use a tapping fluid rated for the workpiece material. Ensure the pilot hole diameter is sized correctly for thread forming, as the required drill size is larger than for a cutting tap of the same thread designation. This tap should be installed and operated by qualified machinists or maintenance technicians familiar with tapping torque requirements and spindle speed settings for the workpiece material. Never use a thread forming tap in cast iron, hardened steel, or other non-ductile materials, as these do not flow and will fracture the tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: 0.08 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: BALAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13446-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972131094834,"sku":"13446-010","price":47.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0aa7b6861b263bea841d1757e1396c29.jpg?v=1789963160","url":"https:\/\/voomisupply.com\/products\/balax-13446-010-thread-forming-tap-3-8-16-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
