Part of the HY-PRO NRT series, it displaces material rather than cutting chips, producing strong formed threads with a smooth finish. The tap features a steam oxide coating for improved lubrication and wear resistance during the forming process. With a bottoming chamfer of 1.5 to 2 threads, it reaches close to the bottom of a blind hole, making it well suited for tight-tolerance work. Overall length is 1.6913 inches with a thread length of 0.3173 inches and a shank diameter of 0.1410 inches. Class of fit is 3B with a thread limit of H2. Installation is performed by machinists and tool-and-die professionals working on precision components.\u003c\/p\u003e\u003cp\u003eThis tap is rated for use on a broad range of materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Its right-hand thread direction and 80 threads per inch pitch make it appropriate for fine-thread blind hole applications in tight clearance assemblies such as instrument hardware, small fastener inserts, and precision machined components. It is suited for use in both manual tapping and CNC machine tapping operations where chip evacuation is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for heat resistance and durability in tough materials including hardened steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves lubrication during thread forming\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (1.5 to 2 threads) allows threading close to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing the risk of chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent Class 3B fit tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 80 threads per inch, UNF standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring a 0-80 UNF right-hand thread at Class 3B fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require proper lubrication or cutting fluid matched to the workpiece material — consult the material application guidelines before use. Ensure the tap is properly aligned with the pilot hole to avoid tap breakage, particularly in small-diameter applications. Power down or disengage the machine spindle before loading or removing the tap. When used in CNC or power tapping applications, verify that the tapping head or rigid tapping cycle is configured for the correct thread pitch to prevent tap breakage.\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: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1.5 to 2P\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\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: 1400100001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731024707890,"sku":"1400100001","price":35.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f03763375c85b2cbb77bd6cbe7e7799b.jpg?v=1788726014","url":"https:\/\/voomisupply.com\/products\/osg-1400100001-thread-forming-tap-0-80-unf-bottoming-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
