Unlike cutting taps, thread forming taps cold-form the thread profile without producing chips, making them well suited for ductile materials where chip evacuation is a concern. This tap is built from high-speed steel with a bright uncoated finish and carries a Thread Limit of H3. It is used by machinists, tool and die makers, and maintenance technicians working on precision small-diameter threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading in small-diameter fastener applications, particularly where a 1-72 UNF thread form is required. The bottoming chamfer style, with 2.5 chamfered threads, allows threading close to the bottom of a blind hole. It fits the BXB series and is appropriate for use in light-gauge metal components, electronic hardware, and instrument assembly where fine-thread engagement is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design cold-forms threads without producing chips, reducing breakage risk in small-diameter work\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 2.5 chamfered threads allows threading close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of ductile workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures consistent fit within Class 2B and 3B tolerance ranges\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction with no oil grooves for straightforward application in standard setups\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.6875 inches suits confined workspaces and small machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for applications requiring a 1-72 UNF Class 2B or 3B internal thread in blind hole configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a specific tap drill size matched to the desired thread form percentage  -  consult a forming tap drill chart before selecting the drill diameter. Use a suitable tapping fluid or cutting oil rated for the workpiece material to reduce forming forces and extend tap life. Always secure the workpiece and use a properly sized tap wrench or CNC holder to maintain axial alignment and prevent tap breakage on this small diameter. Ensure the machine or tool is fully de-energized and the workpiece is fixtured securely before beginning the tapping operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-72 (No. 1)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B, 3B\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\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 1.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 0\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: 0.01 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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10243-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972195516722,"sku":"10243-010","price":46.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04583a52c1f28e36bcb649fc17131725.jpg?v=1789964181","url":"https:\/\/voomisupply.com\/products\/balax-10243-010-thread-forming-tap-1-72-unf-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
