Part of the HY-PRO NRT series, it cuts a 6-40 UNF thread profile with a plug chamfer and a 4 to 4.5 thread chamfer length. Made from cobalt high-speed steel with a TiN coating, it is built to handle harder workpiece materials while maintaining edge life under production conditions. Overall length is 2 inches, with a thread length of 0.37 inches and a tapping depth of 0.685 inches. The H3 thread limit and 3B class of fit make it suitable for standard UNF tolerance applications. Licensed machinists and tool-and-die professionals are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations on a range of ferrous and non-ferrous materials including alloy steel, carbon steel, stainless steel, die steel, hardened steel, and aluminum. The plug chamfer style makes it a general-purpose choice for starting threads in a pre-drilled through hole. It is commonly used in machine shop environments, toolroom work, and production threading on CNC or manual tapping equipment. Material application codes P and N indicate suitability for steel and non-ferrous material groups per standard machinability classifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 UNF right-hand thread profile with plug chamfer and 4 to 4.5 chamfered threads\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in production threading\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with 3B class of fit for standard UNF tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eThrough-hole application with a tapping depth of 0.685 inches\u003c\/li\u003e\n  \u003cli\u003ePart of the OSG HY-PRO NRT series, designed for thread forming without chip generation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole thread forming in alloy steel, carbon steel, stainless steel, die steel, hardened steel, and aluminum workpieces requiring a 6-40 UNF, 3B class of fit thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps are installed by machinists using CNC machining centers, drill presses, or manual tapping arms. Ensure the pilot hole diameter is correctly sized for thread forming, as forming taps displace material rather than cut chips and require a different drill size than cutting taps. Power down and secure all equipment before changing or inspecting tooling. Follow applicable shop safety standards and manufacturer feed and speed recommendations for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\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: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-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\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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.37 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.685 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1400113105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734762127666,"sku":"1400113105","price":34.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_2b6a653d-69e4-4262-873d-a0b1ddd3f063.jpg?v=1788766736","url":"https:\/\/voomisupply.com\/products\/osg-1400113105-thread-forming-tap-6-40-unf-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
