Unlike cutting taps, thread forming taps cold-form the thread profile without removing material, resulting in stronger threads with no chips to evacuate. This tap is manufactured from high-speed steel with a bright uncoated finish and carries an H5 thread limit, making it appropriate for close-tolerance threading work. At 1.75 inches overall length with a 0.4375-inch thread length, it fits standard tap handles and machine setups used by machinists and maintenance technicians working with small-diameter fastener threads.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in ductile and malleable materials where chip-free forming is preferred. The bottoming chamfer, ground to approximately 2.5 threads, allows the tap to form threads close to the bottom of a blind hole. It is used in production and repair environments where 2-56 UNC threaded holes are required in small assemblies, instrument housings, or electronic enclosures. The Series BXB designation identifies this as part of BALAX's thread forming line built for reliability in small-pitch applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces chip-free 2-56 UNC threads ideal for blind holes\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 2.5P lead for threading close to hole bottom\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability in production use\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for controlled tolerance threading\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003cli\u003eNo oil grooves  -  optimized for forming rather than cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a forming tap replacement for blind hole 2-56 UNC threading operations where a bottoming chamfer and H5 thread limit are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a slightly larger pilot hole than cutting taps  -  consult a thread forming drill chart for the correct forming drill size for 2-56 UNC before use. Adequate lubrication is essential; use a tapping fluid appropriate for the workpiece material. Secure the workpiece and ensure the tap is driven square to the hole to avoid tap breakage, especially at this small diameter. This tap is intended for use by machinists or qualified maintenance personnel familiar with small-diameter tapping operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 0\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: 0.02 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: 10285-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52059712323890,"sku":"10285-010","price":45.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f6ee82e57ab6fbea6478630c55f33a2.jpg?v=1790040535","url":"https:\/\/voomisupply.com\/products\/balax-10285-010-thread-forming-tap-2-56-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
