Manufactured from cobalt high-speed steel and coated with titanium carbonitride (TiCN), this tap is built for demanding threading applications where heat and wear resistance are critical. It carries a 5\/8-11 UNC thread specification with a modified bottoming chamfer of 2 to 2.5 chamfered threads, allowing it to thread closer to the bottom of a blind hole than a standard taper or plug chamfer. With an H5 thread limit, it produces threads within a controlled tolerance range suited for precision fit requirements. Licensed machinists and tool and die professionals are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole threading operations in a range of metals including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Its modified bottoming chamfer makes it well suited for applications where full thread engagement close to the bottom of a blind hole is required. The TiCN coating extends tool life in abrasive and high-hardness materials. It is part of the OSG HY-PRO NRT series, which is engineered specifically for thread forming in ductile metals where chipless threading is preferred to reduce the risk of chip contamination in the workpiece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for increased heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive and high-hardness materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5 chamfered threads) allows threading close to blind hole bottoms\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit provides controlled tolerance for precision thread fit applications\u003c\/li\u003e\n  \u003cli\u003eChipless thread forming eliminates chip generation, reducing contamination risk in blind holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard machine and hand tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Adequate lubrication or tapping fluid is essential when forming threads, particularly in steel and stainless steel. Ensure the workpiece and tapping fixture are securely clamped before operation. Always power down or de-energize machine tooling before changing or inspecting taps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 11\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\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.8130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.0906 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 2.1260 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.3600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.5625 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: TiCN\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 14001\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.285 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: 1400150008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731751502130,"sku":"1400150008","price":122.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_ecc62c3e-931f-464b-ac17-a0dc428d9974.jpg?v=1788734543","url":"https:\/\/voomisupply.com\/products\/osg-1400150008-thread-forming-tap-5-8-11-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
