Manufactured from cobalt high-speed steel with a bright finish and an H3 thread limit, this tap produces strong, work-hardened threads by displacing material rather than cutting it. The 12-24 UNC configuration with a modified bottoming chamfer of 2 to 2.5 chamfered threads allows threading close to the bottom of a blind hole. Overall length is 2.375 inches with a tapping depth of 0.933 inches. Licensed machinists and toolroom technicians use this tap in CNC and manual tapping applications across a range of metals.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in alloy steel, carbon steel, aluminum, die steel, hardened steel, and stainless steel workpieces. The modified bottoming chamfer makes it particularly useful in production environments where thread depth close to the floor of a blind hole is required. Right-hand thread direction is standard. Material application codes P and N confirm suitability for steel and non-ferrous materials. The HY-PRO NRT series is a recognized OSG product line for thread forming in demanding industrial and toolroom settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, producing chip-free, work-hardened threads\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 threads) for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent fit in standard UNC tolerance applications\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coolant-through requirement, compatible with flood or manual lubrication\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread, 12-24 UNC, suitable for a broad range of workpiece materials including stainless steel and hardened steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Always use a tapping fluid or cutting oil appropriate for the workpiece material, as thread forming generates higher torque than cutting taps. Secure the workpiece and ensure proper tap alignment before engaging to prevent tap breakage. Power down or de-energize any CNC spindle before manually inspecting or changing 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\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\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: 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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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: 0.025 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: 1400122100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749358108978,"sku":"1400122100","price":31.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c49259a9a232267e18168794f2cdf15.jpg?v=1788904946","url":"https:\/\/voomisupply.com\/products\/osg-1400122100-thread-forming-tap-12-24-unc-cobalt-h3","provider":"Voomi Supply","version":"1.0","type":"link"}
