Part of the HY-PRO NRT series, it uses a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing threading close to the bottom of a blind hole. The tap is manufactured from cobalt high-speed steel and features a titanium nitride (TiN) coating, providing increased surface hardness and extended tool life in demanding materials. At 1.6913 inches overall length with a shank diameter of 0.1410 inches, this tap is sized for precision small-diameter work. It carries a Class 3B fit with an H2 thread limit, making it suitable for tight-tolerance threaded assemblies.\u003c\/p\u003e\u003cp\u003eThis tap is suited for machining operations in manufacturing, toolroom, and maintenance environments where fine 0-80 UNF threads are required in blind holes. It is appropriate for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. The right-hand thread direction and modified bottoming chamfer make it a practical choice for close-tolerance blind hole threading where thread depth is critical. Machinists and tool-and-die professionals working with small fastener threads will find this tap sized for precision fixture and instrument work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0-80 UNF thread form with right-hand direction and Class 3B fit, H2 thread limit\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for threading near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for performance in hardened and stainless steel\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces wear in abrasive materials\u003c\/li\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads with no chip generation\u003c\/li\u003e\n\u003cli\u003eCompatible material applications include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading operations requiring 0-80 UNF threads in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces, per material application codes P and N.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed and operated by qualified machinists familiar with small-diameter tapping procedures. Power down all equipment before changing tooling. Use appropriate tapping fluid or cutting compound recommended for the workpiece material, particularly when tapping stainless or hardened steel. Ensure the tap is properly aligned with the pilot hole to prevent breakage, which is a significant risk at this small diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6913 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3173 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.3500 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\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1400100205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727852011826,"sku":"1400100205","price":39.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3a603507524346baca2c05ed9437a21.jpg?v=1788683518","url":"https:\/\/voomisupply.com\/products\/osg-1400100205-thread-forming-tap-0-80-unf-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
