Part of the HY-PRO NRT series, it uses a bottoming chamfer with 1.5 to 2 chamfered threads, allowing threads to be formed close to the bottom of a blind hole. The tap is manufactured from cobalt high-speed steel and carries a TiCN coating for improved wear resistance and heat tolerance. Overall length is 1.6913 inches, with a thread length of 0.3173 inches and a tapping depth of 0.3500 inches. Right-hand thread direction and a Class 2B fit with H3 thread limit are standard. Installation requires a matching tap wrench or machine holder appropriate for the 0.1410-inch shank diameter.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance threading in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The bottoming chamfer configuration makes it the correct choice when full threads are needed at the base of a blind hole, a common requirement in precision machining, toolroom work, and equipment repair across industrial and manufacturing environments. Machinists, toolmakers, and maintenance technicians working with small-diameter fastener threads in the 0-80 UNF range will find this tap appropriate for both manual and machine tapping operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer with 1.5 to 2 chamfered threads for threading close to blind hole bottoms\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for strength in tough and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in alloy, stainless, and hardened steels\u003c\/li\u003e\n\u003cli\u003eH3 thread limit with Class 2B fit for standard tolerance threading\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 80 threads per inch, 0-80 UNF specification\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design; suitable for hand or machine tapping with applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring 0-80 UNF internal threads at a Class 2B fit.

Power down or disengage the spindle before securing the tap in the holder. Apply an appropriate cutting fluid for the workpiece material before tapping, particularly when working with stainless or hardened steel. Do not exceed the rated tapping depth and back the tap out carefully to avoid breakage in small-diameter blind holes.\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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\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 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: 0.01 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: 1400100108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755602903346,"sku":"1400100108","price":42.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21a04163153912292ef3880df3248164.jpg?v=1788956703","url":"https:\/\/voomisupply.com\/products\/osg-1400100108-thread-forming-tap-0-80-unf-bottoming-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
