Built from cobalt high-speed steel and finished with a titanium nitride (TiN) coating, this tap delivers extended tool life and improved resistance to heat and wear. It is configured as a bottoming chamfer with 1.5 to 2 chamfered threads, allowing threads to be formed close to the bottom of a blind hole. At 0-80 UNF, it produces fine unified threads in small-diameter applications. Overall length is 1.6913 inches with a shank diameter of 0.1410 inches. This tap is part of the HY-PRO NRT series and is sized for precision machining and assembly work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading blind holes in a range of metallic workpiece materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. It is commonly used in precision manufacturing, instrument assembly, and aerospace or electronics fabrication where small UNF threads are required. The bottoming configuration makes it well-suited for applications where thread depth must extend near the base of a drilled hole and a standard or plug chamfer cannot reach. Machinists and tool-and-die professionals working with tapping machines, CNC machining centers, or hand-held tapping equipment will find this tool appropriate for high-accuracy, fine-thread work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design prevents chip buildup in blind holes and reduces tap breakage risk\u003c\/li\u003e\n\u003cli\u003eCobalt HSS construction provides elevated heat resistance compared to standard M2 HSS taps\u003c\/li\u003e\n\u003cli\u003eTiN coating improves surface hardness and reduces friction during the tapping cycle\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1.5 to 2 chamfered threads allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and Class 2B fit for consistent, controlled thread tolerance output\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread forming tap for blind hole threading applications in materials coded P and N, corresponding to steels and non-ferrous metals, as specified by the manufacturer for the HY-PRO NRT series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a properly sized forming tap drill hole, which differs from a standard cut tap drill size and must be selected according to the specific material and thread specification. Secure the tap in a tapping chuck or rigid holder with appropriate torque control to avoid overloading the small shank at this diameter. Always apply a suitable cutting or tapping fluid for the workpiece material before tapping. Follow applicable machine safety procedures and ensure the workpiece is securely fixtured before beginning the tapping cycle.\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 Type\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: 2B\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\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\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\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\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: 1400100105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738459668786,"sku":"1400100105","price":38.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e931b2ebaee888e3186030e13882a2a2.jpg?v=1788799800","url":"https:\/\/voomisupply.com\/products\/osg-1400100105-thread-forming-tap-0-80-unf-bottoming-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
