Part of the HY-PRO NRT series, this tap is configured in a 12-24 UNC right-hand thread with a modified bottoming chamfer of 2 to 2.5 threads, making it well suited for threading close to the bottom of a blind hole. Built from cobalt high-speed steel with a bright finish, it carries a thread limit of H2 and delivers consistent thread geometry in a range of ferrous and non-ferrous materials. Overall length is 2.375 inches with a shank diameter of 0.220 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is used for blind hole threading applications across general machining, toolroom, and production environments. Its material application range covers alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel, making it versatile for job shops and production floors handling mixed material workloads. The modified bottoming chamfer allows threading to near-full depth in shallow blind holes where a standard taper or plug chamfer would leave insufficient thread engagement. It is typically installed in CNC machining centers, turret lathes, or manual tapping setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads with no chips to clear\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) for threading close to blind hole bottoms\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent tolerance control in precision threading applications\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coolant-through requirement, suitable for standard tapping fluid application\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread, 24 TPI, compatible with 12-24 UNC tapped hole standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring a 12-24 UNC internal thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed by a qualified machinist in a rigid tapping setup or tapping head capable of maintaining axial alignment with the pre-drilled pilot hole. Use an appropriate tapping fluid or cutting oil matched to the workpiece material before beginning the tapping cycle. Ensure the machine spindle and workpiece are secure before engaging the tap, and do not exceed the recommended feed rate for the tap size to avoid breakage or thread distortion. Always de-energize and lock out the machine before changing or inspecting the tap.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5 threads\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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.933 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.220 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2813 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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1400122000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739265827122,"sku":"1400122000","price":31.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_583ce22f-7175-40a0-98d4-2f6a84288258.jpg?v=1788812411","url":"https:\/\/voomisupply.com\/products\/osg-1400122000-thread-forming-tap-12-24-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
