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 finished with a steam oxide coating for improved lubricity and wear resistance. It carries a Class 3B thread fit with an H3 thread limit, making it suitable for precision threading work. At 2.125 inches overall length and 0.168 inches shank diameter, it fits standard tap holders used in machining and fabrication environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading alloy steel, carbon steel, die steel, hardened steel, aluminum, and stainless steel workpieces. It is used in blind hole threading operations where a standard plug tap cannot reach the required depth. Typical applications include production machining, tool-and-die work, and precision fabrication where 8-32 UNC threads must be formed close to the bottom of a drilled hole. Right-hand thread direction applies. The cobalt construction supports use on harder and more abrasive materials where standard high-speed steel taps wear prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for near-bottom blind hole threading\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for durability on alloy steel, hardened steel, and stainless steel\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and reduces galling during thread forming\u003c\/li\u003e\n\u003cli\u003eH3 thread limit, Class 3B fit for precision tolerance control\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 32 threads per inch, 8-32 UNC specification\u003c\/li\u003e\n\u003cli\u003eNo coolant-through feature; suited for use with cutting fluid applied externally\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 8-32 UNC internal threads to Class 3B fit standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps should be installed by machinists or tool-and-die professionals using a properly sized tap holder or CNC tapping attachment. Power down and secure the workpiece before starting. Use appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Verify pilot hole diameter against the recommended tap drill size for 8-32 UNC thread forming before beginning the operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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: H3\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: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.250 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 1400114301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731962069298,"sku":"1400114301","price":30.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/804e87e2da0225a3b65b2ef495710b90.jpg?v=1788737293","url":"https:\/\/voomisupply.com\/products\/osg-1400114301-thread-forming-tap-8-32-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
